Induced Mesenchymal stromal cells derived from iPS cells from aged individuals acquire a rejuvenation signature and a MSC-specific secretome

ABSTRACT: Human induced pluripotent stem cells (iPSCs) - derived mesenchymal stromal cells (iMSCs) are a potentially useful cell type for circumventing ageing-related shortfalls associated with primary mesenchymal or skeletal stromal cells (MSCs/SSCs). To date, the extent of the reflection of ageing-hallmarks in iMSCs differentiated from iPSCs derived from elderly donors remains unclear. In this study, we show that fetal (55 days post conception) femur-derived MSCs and MSCs isolated from aged (60 – 74 years) donors differ in their transcriptome and secretome profile. Yet, iMSCs irrespective of donor age and cell type acquired a rejuvenation gene signature, specifically, INHBE, DNMT3B, POU5F1P1, CDKN1C, GCNT2; also present in pluripotent stem cells but not observed in the parental MSCs. Furthermore, dendrograms generated from the transcriptomes of iMSCs derived from the human embryonic stem cell line H1, fetal and aged MSCs always clustered together with the parental fetal femur-derived MSCs. In addition, these were distinct from MSCs isolated from aged donors when comparing gene ontologies (GOs) related to ageing processes. Critically, in terms of regenerative medicine applications, iMSCs re-acquired a similar secretome (e.g. SERPINE1, SDF-1a, HGF, IL6, IL10, THBS1) to that of the parental fetal MSCs, thus re-enforcing their capabilities of imparting context dependent paracrine signaling.

Project description:Background: Radiation therapy is the standard of care for central nervous system tumours. Despite the success of radiation therapy in reducing tumour mass, irradiation (IR)-induced vasculopathies and neuroinflammation contribute to late-delayed complications, neurodegeneration, andpremature ageing in long-term cancer survivors. Mesenchymal stromal cells (MSCs) are adult stem cells that facilitate tissue integrity, homeostasis, and repair. Here, we investigated the potential of the iPSC-derived MSC(iMSC) secretome in immunomodulation and vasculature repair in response to radiation injury utilizing human cell lines. Methods: We generated iPSC-derived iMSC lines and evaluated the potential of their conditioned media (iMSC CM) to treat IR-induced injuries in human monocytes (THP1) and brain vascular endothelial cells (hCMEC/D3). We further assessed factors in the iMSC secretome, their modulation, and the molecular pathways they elicit. Results: Increasing doses of IR disturbed endothelial tube and spheroid formation in hCMEC/D3. When IR-injured hCMEC/D3 (IR ≤ 5 Gy) were treated with iMSC CM, endothelial cell viability, adherence, spheroid compactness, and proangiogenic sprout formation were significantly ameliorated, and IR-induced ROS levels were reduced. iMSC CM augmented tube formation in cocultures of hCMEC/D3 and iMSCs. Consistently, iMSC CM facilitated angiogenesis in a zebrafish model in vivo. Furthermore, iMSC CM suppressed IR-induced NFκB activation, TNF-α release, and ROS production in THP1 cells. Additionally, iMSC CM diminished NF-kB activation in THP1 cells cocultured with irradiated hCMEC/D3, iMSCs, or HMC3 microglial lines. The cytokine array revealed that iMSC CM contains the proangiogenic and immunosuppressive factors MCP1/CCL2, IL6, IL8/CXCL8, ANG (Angiogenin), GROα/CXCL1, and RANTES/CCL5. Common promoter regulatory elements were enriched in TF-binding motifs such as androgen receptor (ANDR) and GATA2. hCMEC/D3 phosphokinome profiling revealed increased expression of pro-survival factors, the PI3K/AKT/mTOR modulator PRAS40 and β-catenin in response to CM. The transcriptome analysis revealed increased expression of GATA2 in iMSCs and the enrichment of pathways involved in RNA metabolism, translation, mitochondrial respiration, DNA damage repair, and neurodevelopment. Conclusions: The iMSC secretome is a comodulated composite of proangiogenic and immunosuppressive factors that has the potential to alleviate radiation-induced vascular endothelial cell damage and immune activation.

Project description:Canine adipose-derived mesenchymal stem cells (cAD-MSCs) show therapeutic promise for their regenerative potential, particularly in their secretome. However, concerns arise regarding the impact of in vitro cultivation need for storing therapeutic doses, prompting this study to comprehensively explore the impact of in vitro aging on gene expression and secretome composition. The study involved collecting abdominal adipose tissue samples from nine healthy female dogs, from which cAD-MSCs were extracted and cultured. Stem cells were validated through trilineage differentiation assays and flow cytometry immunophenotyping. Gene expression profiling, using RT-qPCR array and cAD-MSCs secretome LC-MS/MS analysis, were conducted at passages 3 and 6 to reveal gene expression and protein composition alterations during in vitro culture. Gene expression profiling of in vitro aged cAD-MSCs revealed expression alterations, while significant downregulation was observed in two MSC-associated genes. Proteomic analysis revealed 10% distinctively expressed proteins, and several up- and downregulations. Grouping these proteins with biologically significant ones, Gene Ontology Panther Pathway analysis revealed that P3 proteins were significantly associated with cytoskeletal regulation, nicotinic acetylcholine receptor signaling, inflammation mediated by chemokine and cytokine signaling, Wnt signaling, and CCKR signaling map. In contrast, P6 proteins were linked to the xanthine and guanine salvage pathway, adenine and hypoxanthine salvage pathway, and blood coagulation pathway. To the best of our knowledge, this study presents the first original perspective on the changes in secretome composition that occur when cAD-MSCs age in vitro. Our findings highlight significant changes that, in conclusion, indicate the regenerative potential of cAD-MSCs and that their secretome may be compromised due to in vitro aging. Consequently, our study suggests a preference for earlier passages when considering these cells for therapeutic applications.
