INDUCTION OF HUMAN MESENCHYMAL STEM CELLS FROM NEONATAL AND ADULT SOURCES BY A SMALL MOLECULE COCKTAIL

Project description:Human mesenchymal stem cells (MSCs) are good candidates for brain cell-replacement strategies and has been already used as adjuvant treatment in neurological disorders. MSCs can be obtained from many different sources, and the present study compares the neuronal potential transdifferentiation of MSCs from adult and neonatal sources with a protocol previously tested, consisting in a cocktail of six small molecules: I-BET151, CHIR99021, Forskolin, RepSox, Y-27632, and dbcAMP (ICFRYA). A neuronal morphology and the presence of cells positive to neuronal markers (TUJ-1 and MAP2) were considered attributes of neuronal induction. The present study showed marked differences between MSCs from different sources in response to the transdifferentiation protocol here used. These results may contribute to identifying the best source of MSCs for potential cell-replacement therapies.

Neuronal Transdifferentiation Potential of Human Mesenchymal Stem Cells from Neonatal and Adult Sources by a Small Molecule Cocktail.

Project description:Human mesenchymal stem cells (MSCs) are good candidates for brain cell replacement strategies and have already been used as adjuvant treatments in neurological disorders. MSCs can be obtained from many different sources, and the present study compares the potential of neuronal transdifferentiation in MSCs from adult and neonatal sources (Wharton's jelly (WhJ), dental pulp (DP), periodontal ligament (PDL), gingival tissue (GT), dermis (SK), placenta (PLAC), and umbilical cord blood (UCB)) with a protocol previously tested in bone marrow- (BM-) MSCs consisting of a cocktail of six small molecules: I-BET151, CHIR99021, forskolin, RepSox, Y-27632, and dbcAMP (ICFRYA). Neuronal morphology and the presence of cells positive for neuronal markers (TUJ1 and MAP2) were considered attributes of neuronal induction. The ICFRYA cocktail did not induce neuronal features in WhJ-MSCs, and these features were only partial in the MSCs from dental tissues, SK-MSCs, and PLAC-MSCs. The best response was found in UCB-MSCs, which was comparable to the response of BM-MSCs. The addition of neurotrophic factors to the ICFRYA cocktail significantly increased the number of cells with complex neuron-like morphology and increased the number of cells positive for mature neuronal markers in BM- and UCB-MSCs. The neuronal cells generated from UCB-MSCs and BM-MSCs showed increased reactivity of the neuronal genes TUJ1, MAP2, NF-H, NCAM, ND1, TAU, ENO2, GABA, and NeuN as well as down- and upregulation of MSC and neuronal genes, respectively. The present study showed marked differences between the MSCs from different sources in response to the transdifferentiation protocol used here. These results may contribute to identifying the best source of MSCs for potential cell replacement therapies.

A core of differentially methylated CpG loci in gMDSCs isolated from neonatal and adult sources

Project description:Using the Illumina EPIC array to measure DNAm of gMDSCs and neutrophils from diverse neonatal and adult blood sources, we found 189 differentially methylated CpGs between gMDSCs and neutrophils with a core of ten differentially methylated CpGs that were consistent across both sources of cells. Genes associated with these loci that are involved in immune responses include VCL, FATS, YAP1, KREMEN2, UBTF, MCC-1, and EFCC1. In two cancer patient groups that reflected those used to develop the methylation markers (head and neck squamous cell carcinoma (HNSCC) and glioma), all of the CpG loci were differentially methylated, reaching statistical significance in glioma cases and controls, while one was significantly different in the smaller HNSCC group. Our findings indicate that gMDSCs have a core of distinct DNAm alterations, informing future research on gMDSC differentiation and function.

Reprogramming of Human Urine Stem Cells into Cardiomyocytes via a Small Molecule Cocktail in Xeno-free conditions

Project description:Reprogramming autologous somatic cells into alternative lineages holds significant promise as a crucial cell source for regenerative therapy. Among various sources, human urine stem cells (hUSCs) have emerged as a highly promising candidate for reprogramming due to their ease of collection and high transdifferentiation potential. In this study, we present the first evidence for cardiac regeneration by directly converting hUSCs into functional cardiomyocytes under xeno-free conditions using a cocktail of 15 small molecules. This innovative protocol ensures a safe, animal-free reprogramming environment, enhancing its clinical applicability. The resulting chemically induced human cardiomyocyte-like cells (hCiCMs) exhibit several key characteristics of native cardiomyocytes, including the expression of cardiomyocyte-specific markers, display sarcomeric organization, and exhibit typical cardiac calcium flux and electrophysiological properties. Notably, transplantation of hCiCMs into the infarcted hearts of mice led to substantial improvements in cardiac function, characterized by enhanced contractility and reduced infarct size. Our findings validate the efficacy of the xeno-free differentiation protocol and highlight the potential of hUSC-derived hCiCMs as a viable and effective source for regenerative therapies in myocardial infarction. The use of hUSCs provides a readily accessible, autologous cell source, thereby paving the way for personalized and safer regenerative treatments for cardiac diseases.
