Improved culture conditions for the growth and detection of Borrelia from human serum.

ABSTRACT: In this report we present a method to cultivate Borrelia spirochetes from human serum samples with high efficiency. This method incorporates improved sample collection, optimization of culture media and use of matrix protein. The method was first optimized utilizing Borrelia laboratory strains, and later by demonstrating growth of Borrelia from sera from fifty seropositive Lyme disease patients followed by another cohort of 72 Lyme disease patients, all of whom satisfied the strict CDC surveillance case definition for Lyme disease. The procedure resulted in positive cultures in 47% at 6 days and 94% at week 16. Negative controls included 48 cases. The positive identification of Borrelia was performed by immunostaining, PCR, and direct DNA sequencing.

Optimized Culture Conditions for Improved Growth and Functional Differentiation of Mouse and Human Colon Organoids.

Project description:Background & aimsDiligent side-by-side comparisons of how different methodologies affect growth efficiency and quality of intestinal colonoids have not been performed leaving a gap in our current knowledge. Here, we summarize our efforts to optimize culture conditions for improved growth and functional differentiation of mouse and human colon organoids.MethodsMouse and human colon organoids were grown in four different media. Media-dependent long-term growth was measured by quantifying surviving organoids via imaging and a cell viability readout over five passages. The impact of diverse media on differentiation was assessed by quantifying the number of epithelial cell types using markers for enterocytes, stem cells, Goblet cells, and enteroendocrine cells by qPCR and histology upon removal of growth factors.ResultsIn contrast to Wnt3a-conditioned media, media supplemented with recombinant Wnt3a alone did not support long-term survival of human or mouse colon organoids. Mechanistically, this observation can be attributed to the fact that recombinant Wnt3a did not support stem cell survival or proliferation as demonstrated by decreased LGR5 and Ki67 expression. When monitoring expression of markers for epithelial cell types, the highest level of organoid differentiation was observed after combined removal of Wnt3a, Noggin, and R-spondin from Wnta3a-conditioned media cultures.ConclusionOur study defined Wnt3a-containing conditioned media as optimal for growth and survival of human and mouse organoids. Furthermore, we established that the combined removal of Wnt3a, Noggin, and R-spondin results in optimal differentiation. This study provides a step forward in optimizing conditions for intestinal organoid growth to improve standardization and reproducibility of this model platform.

Assessment of new culture method for detection of Borrelia species from serum of lyme disease patients.

Project description:A novel method of culturing spirochetes from the serum of U.S. Lyme disease patients was recently reported by Sapi and colleagues to have 94% sensitivity and 100% specificity for Borrelia species as assessed by microscopy and DNA sequence analysis of the pyrG gene (E. Sapi, N. Pabbati, A. Datar, E. M. Davies, A. Rattelle, and B. A. Kuo, Int. J. Med. Sci. 10:362-376, 2013). The majority of the spirochetes described were related by pyrG sequences to species of Borrelia previously undetected in North American patients without a reported history of travel to Europe or Asia. To better understand these unexpected findings, we determined pyrG sequences of the laboratory reference strains used by the investigators for method development and testing of culture medium. Eighty percent (41/51) of the reported patient-derived pyrG sequences were identical to one of the laboratory strains, and an additional 12% (6/51) differed by only a single nucleotide across a 603-bp region of the pyrG gene. Thus, false positivity due to laboratory contamination of patient samples cannot be ruled out, and further validation of the proposed novel culture method is required.

Purified human pancreatic duct cell culture conditions defined by serum-free high-content growth factor screening.

Project description:The proliferation of pancreatic duct-like CK19+ cells has implications for multiple disease states including pancreatic cancer and diabetes mellitus. The in vitro study of this important cell type has been hampered by their limited expansion compared to fibroblast-like vimentin+ cells that overgrow primary cultures. We aimed to develop a screening platform for duct cell mitogens after depletion of the vimentin+ population. The CD90 cell surface marker was used to remove the vimentin+ cells from islet-depleted human pancreas cell cultures by magnetic-activated cell sorting. Cell sorting decreased CD90+ cell contamination of the cultures from 34±20% to 1.3±0.6%, yielding purified CK19+ cultures with epithelial morphology. A full-factorial experimental design was then applied to test the mitogenic effects of bFGF, EGF, HGF, KGF and VEGF. After 6 days in test conditions, the cells were labelled with BrdU, stained and analyzed by high-throughput imaging. This screening assay confirmed the expected mitogenic effects of bFGF, EGF, HGF and KGF on CK19+ cells and additionally revealed interactions between these factors and VEGF. A serum-free medium containing bFGF, EGF, HGF and KGF led to CK19+ cell expansion comparable to the addition of 10% serum. The methods developed in this work should advance pancreatic cancer and diabetes research by providing effective cell culture and high-throughput screening platforms to study purified primary pancreatic CK19+ cells.

Propagation of goat putative spermatogonial stem cells under growth factors defined serum-free culture conditions.

Project description:In the present study, we used a serum-free culture media to propagate goat putative spermatogonial stem cells (SSCs) and evaluated the effect of crucial growth factors on relative expression of some SSC markers and self-renewal related genes. The enriched SSCs were cultured on a homologous Sertoli cell feeder layer in KO-DMEM supplemented with 10% KOSR. Putative SSC colonies emerged between day 6 and 10 which were then characterized by the expression of numerous spermatogonial and pluripotency related markers. After 15 days of subculture, the relative mRNA expression study revealed that 40 ng/mL concentration of Glial cell line-derived neurotrophic factor (GDNF) upregulated the expression of BCL6B, ID4, PLZF, and UCHL1. Moreover, the supplementation of GDNF + bFGF up-regulated the expression of PLZF and BCL6B. UCHL1 expression was higher after addition of GDNF + LIF while, THY1 overexpressed in response to the addition of GDNF + CSF1. These results demonstrated that the goat SSCs were efficiently propagated using a KOSR based serum-free media and the growth factor supplementation markedly influences their gene expression profile.

Surface-engineered substrates for improved human pluripotent stem cell culture under fully defined conditions.

Project description:The current gold standard for the culture of human pluripotent stem cells requires the use of a feeder layer of cells. Here, we develop a spatially defined culture system based on UV/ozone radiation modification of typical cell culture plastics to define a favorable surface environment for human pluripotent stem cell culture. Chemical and geometrical optimization of the surfaces enables control of early cell aggregation from fully dissociated cells, as predicted from a numerical model of cell migration, and results in significant increases in cell growth of undifferentiated cells. These chemically defined xeno-free substrates generate more than three times the number of cells than feeder-containing substrates per surface area. Further, reprogramming and typical gene-targeting protocols can be readily performed on these engineered surfaces. These substrates provide an attractive cell culture platform for the production of clinically relevant factor-free reprogrammed cells from patient tissue samples and facilitate the definition of standardized scale-up friendly methods for disease modeling and cell therapeutic applications.

Effects of Macromolecular Crowding on Human Adipose Stem Cell Culture in Fetal Bovine Serum, Human Serum, and Defined Xeno-Free/Serum-Free Conditions.

Project description:Microenvironment plays an important role for stem cell proliferation and diﬀerentiation. Macromolecular crowding (MMC) was recently shown to assist stem cells in forming their own matrix microenvironment in vitro. The ability of MMC to support adipose stem cell (ASC) proliferation, metabolism, and multilineage diﬀerentiation was studied under diﬀerent conditions: fetal bovine serum- (FBS-) and human serum- (HS-) based media and xeno- and serum-free (XF/SF) media. Furthermore, the immunophenotype of ASCs under MMC was evaluated. The proliferative capacity of ASCs under MMC was attenuated in each condition. However, osteogenic diﬀerentiation was enhanced under MMC, shown by increased deposition of mineralized matrix in FBS and HS cultures. Likewise, signiﬁcantly greater lipid droplet accumulation and increased collagen IV deposition indicated enhanced adipogenesis under MMC in FBS and HS cultures. In contrast, chondrogenic diﬀerentiation was attenuated in ASCs expanded under MMC. The ASC immunophenotype was maintained under MMC with signiﬁcantly higher expression of CD54. However, MMC impaired metabolic activity and diﬀerentiation capacity of ASCs in XF/SF conditions. Both the supportive and inhibitory eﬀects of MMC on ASC are culture condition dependent. In the presence of serum, MMC maintains ASC immunophenotype and enhances adipogenic and osteogenic diﬀerentiation at the cost of reduced proliferation.

Quantification of Borrelia burgdorferi Membrane Proteins in Human Serum: A New Concept for Detection of Bacterial Infection.

Project description:The Borrelia burgdorferi spirochete is the causative agent of Lyme disease, the most common tick-borne disease in the United States. The low abundance of bacterial proteins in human serum during infection imposes a challenge for early proteomic detection of Lyme disease. To address this challenge, we propose to detect membrane proteins released from bacteria due to disruption of their plasma membrane triggered by the innate immune system. These membrane proteins can be separated from the bulk of serum proteins by high-speed centrifugation causing substantial sample enrichment prior to targeted protein quantification using multiple reaction monitoring mass spectrometry. This new approach was first applied to detection of B. burgdorferi membrane proteins supplemented in human serum. Our results indicated that detection of B. burgdorferi membrane proteins, which are ≈10(7) lower in abundance than major serum proteins, is feasible. Therefore, quantitative analysis was also carried out for serum samples from three patients with acute Lyme disease. We were able to demonstrate the detection of ospA, the major B. burgdorferi lipoprotein at the level of 4.0 fmol of ospA/mg of serum protein. The results confirm the concept and suggest that the proposed approach can be expanded to detect other bacterial infections in humans, particularly where existing diagnostics are unreliable.

Detection of Borrelia burgdorferi Cell-free DNA in Human Plasma Samples for Improved Diagnosis of Early Lyme Borreliosis.

Project description:BackgroundLaboratory confirmation of early Lyme borreliosis (LB) is challenging. Serology is insensitive during the first days to weeks of infection, and blood polymerase chain reaction (PCR) offers similarly poor performance. Here, we demonstrate that detection of Borrelia burgdorferi (B.b.) cell-free DNA (cfDNA) in plasma can improve diagnosis of early LB.MethodsB.b. detection in plasma samples using unbiased metagenomic cfDNA sequencing performed by a commercial laboratory (Karius Inc) was compared with serology and blood PCR in 40 patients with physician-diagnosed erythema migrans (EM), 28 of whom were confirmed to have LB by skin biopsy culture (n = 18), seroconversion (n = 2), or both (n = 8). B.b. sequence analysis was performed using investigational detection thresholds, different from Karius' clinical test.ResultsB.b. cfDNA was detected in 18 of 28 patients (64%) with laboratory-confirmed EM. In comparison, sensitivity of acute-phase serology using modified 2-tiered testing (MTTT) was 50% (P = .45); sensitivity of blood PCR was 7% (P = .0002). Combining B.b. cfDNA detection and MTTT increased diagnostic sensitivity to 86%, significantly higher than either approach alone (P ≤ .04). B.b. cfDNA sequences matched precisely with strain-specific sequence generated from the same individual's cultured B.b. isolate. B.b. cfDNA was not observed at any level in plasma from 684 asymptomatic ambulatory individuals. Among 3000 hospitalized patients tested as part of clinical care, B.b. cfDNA was detected in only 2 individuals, both of whom had clinical presentations consistent with LB.ConclusionsThis is the first report of B.b. cfDNA detection in early LB and a demonstration of potential diagnostic utility. The combination of B.b. cfDNA detection and acute-phase MTTT improves clinical sensitivity for diagnosis of early LB.

Improved protease digestion conditions for membrane protein detection.

Project description:This work presents improved protease digestion conditions for membrane protein detection. The enzymatic digest of bacteriorhodopsin (BR), a model membrane protein with seven transmembrane domains (TMDs) was investigated. An initial in-gel digestion identified 17% BR sequence coverage, including part of the seventh TMD. To improve sequence coverage, BR digest was tested with different concentrations of RapiGest, methanol (MeOH) and SDS using either trypsin or chymotrypsin. Two improved conditions, 0.01% SDS or the combination of 10% MeOH and 0.01% RapiGest, were chosen. Trypsin digestions in both conditions achieved more than 40% BR sequence coverage compared to 0% using standard digestion conditions. Peptides detected from trypsin and chymotrypsin digestions in the same condition were combined to maximize sequence coverage. The same conditions were applied to a different membrane protein with one TMD, Selenoprotein S, and proteins from Escherichia coli. For Selenoprotein S, a higher sequence coverage, including a peptide from the TMD, was detected from the improved condition compared to the typical condition. The application of both improved conditions to a membrane protein fraction of Escherichia coli resulted in the identification of 309 (SDS) and 329 (MeOH/RapiGest) unique proteins of which 140/309 and 148/329 were membrane proteins.
