Comprehensive analysis of the secretome and transcriptome stability from WJ-Mesenchymal Stromal cells throughout GMP-Manufacturing

ABSTRACT: Mesenchymal stromal cells (MSCs) hold promise for cell-based therapies due to their ability to stimulate tissue repair and modulate immune responses. Umbilical cord-derived MSC from Wharton’s jelly (WJ), offer advantages such as low immunogenicity and potent immune modulatory effects. However, ensuring consistent quality and safety throughout their manufacturing process remains critical. RNA sequencing (RNA-seq) emerges as a crucial tool for assessing genetic stability and expression dynamics. This study examines the secretome and transcriptome signatures throughout WJ-MSCs Good Manufacturing Practice (GMP) production, focusing in the role of Total RNA or Massive Analysis of cDNA Ends (MACE-Seq)-RNA sequencing. Through comprehensive transcriptomic analysis, we demonstrated the stability of WJ-MSC transcriptome across manufacturing stages. Notably, MACE-Seq enhanced the identification of key expression patterns related to senescence and immunomodulation. These findings highlight the potential of MACE-Seq as a routine quality assessment tool for WJ-MSC-based therapies, ensuring their efficacy and safety in clinical applications. Importantly, MACE-Seq proves valuable for characterizing WJ-MSC products, providing insights unattainable through traditional assays.

Quantitative proteomics analysis of different sources of hMSCs

Project description:Mesenchymal stem cells (MSCs) are an attractive therapeutic tool for tissue engineering and re-generative medicine due to their regenerative and trophic properties. The best-known and most widely used are bone marrow MSCs, but they are now being harvested and developed from a wide range of adult and perinatal tissues. MSCs from different sources are believed to have dif-ferent secretion potentials and production, which may influence their therapeutic effects. To prove it, we performed a quantitative proteomic analysis based on the TMT technique of MSCs from 3 different sources: wharton’s jelly (WJ), dental pulp (DP) and bone marrow (BM). Our analysis has focused on MSC biological properties of interest for tissue engineering. We identified a total of 611 human proteins differentially expressed. WJ-MSCs shown the greatest variation compared to the other sources. WJ produced more extra-cellular matrix (ECM) proteins and ECM-affiliated proteins and appeared to more able to modulate the inflammatory and immune response. BM-MSCs display enhanced differentiation and paracrine communication capabilities. DP-MSC appeared to promote exosome production. The results obtained confirm the existence of differences between WJ, DP and BM-MSC and the need to select the MSC origin according to the therapeutic objective sought.

miR-146a-5p circuitry uncouples cell proliferation and migration, but not differentiation, in human mesenchymal stem cells

Project description:Administration of mesenchymal stem cells (MSCs) has the potential to ameliorate degenerative disorders and to repair damaged tissues. The homing of transplanted MSCs to injured sites is a critical property of engraftment. Our aim was to identify microRNAs involved in controlling MSC proliferation and migration. MSCs can be isolated from bone marrow and umbilical cord Wharton's jelly (BM-MSCs and WJ-MSCs, respectively), and WJ-MSCs show poorer motility yet have a better amplification rate compared to BM-MSCs. One human BM-MSC (pooled sample of 4 independent donors), one human WJ-MSC (pooled sample of 3 independent donors), and differentiated osteocytes and adipocytes derived from BM-MSCs after 2 weeks induction.

Gene expression profile of Wharton-jelly mesenchymal stem cells at 12th in vitro expansion cycle compared to Wharton-jelly mesenchymal stem cells at 4th in vitro expansion cycle

Project description:Mesenchymal stem cells (MSCs) are generally considered the main tool box for cell-based therapies and compared to embryonic stem cells (ESCs), MSCs exhibit many advantages. It has been shown that UC matrix (the Wharton’s Jelly surrounding umbilical vessels) contains a great number of mesenchymal cells. The abundant amount of Wharton’s Jelly (WJ) makes it an attractive source of MSCs for cell-based therapies. recently have been highlighted the changes in protein expression profiling during in vitro expansion of WJ-MSC, probably related to the gradual reduction of their staminal plasticity and to the biological cellular mechanism occurring in the cellular aging. The aim of the present work was to analyze the transcriptomic profile useful to the definition of WJ-MSC characteristics and therefore identify possible different new marker candidates. In these contest, changes in gene expression profiles occurring during WJ-MSC in vitro growth wile by analyzed in order to find possible modulation related to their long expansion and fast growth abilities. We analyzed the changes in total RNA expression at the 12th in vitro expansion cycle compared to the 4th in vitro expansion cycle.

Isolation and comparative analysis of mesenchymal stem cells from human umbilical cord II

Project description:A non-controversial and non-invasive source of adult stem cells (ASCs), particularly hematopoietic stem cells (HSCs) and mesenchymal stem cells (MSCs) is human umbilical cord blood. HSCs derived from cord blood have been used for treating leukemia and other blood disorders for the last 30 years. While the presence of MSCs in cord blood is limited, umbilical cord has been found to be promising source of MSCs. However, the cord is an anatomically complex organ and potential isolation of MSCs from its various parts has not been fully explored. In this study we dissected the cord into cord placenta junction (CPJ), cord tissue (CT), and Wharton’s jelly (WJ) and isolated stem cells. These cells exhibited fibroid morphology, expressed MSC-specific markers including CD90, CD73, CD105, CD44, and CD29 and differentiated into chondrogenic, osteogenic, and adipogenic lineages. In addition, they all expressed pluripotency genes, OCT4, Nanog, Sox2 and KLF4 but expression of these markers was highest in CPJ followed by WJ and CT. CPJ-MSCs also had higher rate of proliferation compared to WJ- and CT-MSCs. Proliferation of WJ- and CT-MSCs was markedly decreased upon passaging with concomitant decrease in expression of MSC and pluripotency markers. Based on their greater self-renewal potential, CPJ-MSCs could be superior to WJ- and CT-MSCs for the applications in therapeutic and regenerative medicine.

Whole transcript expression profiling of umbilical cord- and bone marrow-derived stem cells

Project description:Mesenchymal stromal cells (MSCs) are multipotent stem cells with potent immunosuppressive and trophic support functions. Although bone marrow is considered the golden standard to isolate classical MSCs (BM-MSC), MSC-like cells are currently also derived from other, more easily accessible extra-embryonic tissues such as the umbilical cord. In this study we compared the gene expression profile of human Wharton's jelly explant-derived MSC cultures with two adult MSC populations derived from bone marrow, namely BM-MSC and multipotent adult progenitor cells (MAPC). Here we demonstrate, by using genome wide gene expression analysis, that WJ-MSCs intrinsically have a differential gene expression profile compared to the adult MSCs. Gene ontology analysis revealed an increased expression of genes associated with cell-adhesion, proliferation, and immune system functioning. Furthermore, in comparison to adult MSC, stem cells from the Wharton’s jelly highly express genes involved in neurotrophic support (e.g. LIF, BDNF, NTF3). Such enhanced signatures make WJ-MSC an attractive candidate for cell-based therapy in neurodegenerative and immune-mediated CNS disorders such as multiple sclerosis or amyotrophic lateral sclerosis.

An insight into Exosomal Cargo Isolated from three tissue specific Mesenchymal Stem Cells: Implication in Translational Research

Project description:Adult Mesenchymal stem cells (MSCs) derived exosomes have recently gained importance as a cell-free therapy for several chronic and inflammatory diseases. It is believed that these exosomes contain several biologically active molecules (i.e. miRNAs, proteins) which help to cure the diseases. The majority of published reports to date that have investigated the secretome of MSCs have done so using canonical expansion of cell culture conditions. However, the microenvironment experience by MSC post administration into animal models and patients is strikingly different. Thus instead of using secretome, Exosomes purified from adipose tissue (AD), Wharton Jelly (WJ) and Bone marrow BM) are widely studied. However, the content of the exosomes may differ based on their sources from where they are originated. It remains unclear, however, which types of proteins are packaged into exosomes compared with the cells from which they are derived. To explore these exosomes as a cell-free therapy for specific diseases, it is therefore, important to get comprehensive knowledge of the bioactive molecules present in the exosomes. In this study, we have purified the exosomes from three different sources (AD, WJ, and BM) and using RNA-Seq approach, we have categorized the common and different microRNAs present in the exosomes.

Gene expression patterns of mesenchymal stem cells from bone marrow and Wharton's jelly of umbilical cord

Project description:Mesenchymal stem cells (MSCs) are promising tools for the treatment of diseases such as infarcted myocardia and strokes because of their ability to promote endogenous angiogenesis and neurogenesis via a variety of secreted factors. MSCs found in the Wharton's jelly of the human umbilical cord are easily obtained and are capable of transplantation without rejection. We isolated MSCs from WhartonM-bM-^@M-^Ys jelly and bone marrow (WJ-MSCs and BM-MSCs, respectively) and compared their transcriptional profiles. In this study, BM-MSCs and WJ-MSCs were isolated from 4 and 3 independent donors, respectively.
