Generation of Human Expandable Limb Bud Cells via Chemically Induced Dedifferentiation Strategy [scRNA-seq]

ABSTRACT: Here, we introduce a novel chemically induced dedifferentiation approach that reverses the cellular development from a differentiated state to progenitor state with reduced senescence features, conferring the generation of limb bud progenitors from human adult mesenchymal stromal cells and dermal fibroblasts. These chemically induced limb bud cells (hCiLB cells) show a high degree of transcriptomic similarity to human embryonic limb bud cells. We found that hCiLB cells can undergo extensive expansion, while maintaining population homogeneity and long-term self-renewal capacity. Moreover, hCiLB cells exhibit increased osteochondrogenic differentiation ability than their parental cells, providing a new platform for the development of authentic articular cartilage. These results also highlight a potential therapeutic approach for the repair of damaged human tissues through reversal of developmental pathways from mature cells to expandable progenitor cells.

Gene expression profile of chemically induced expandable cardiovascular progenitor cells derived from mouse fibroblasts

Project description:Cardiovascular progenitor cells (CPCs) can be reprogrammed from somatic fibroblasts by combinations of genes, providing a new avenue for cardiac regenerative therapy. Here we developed a strategy to capture chemically induced CPCs (ciCPCs) during the small molecule-induced cardiac reprogramming of mouse fibroblasts and expand these ciCPCs for a long-term in a chemically defined condition. RNA-seq analysis has been used to compare the expression profile of ciCPCs at early and late passages.

Self-renewal of hepatoblasts under chemically defined conditions by reiterative growth factor and chemical screening

Project description:Throught an reiterative growth factor and chemical screening, we defined a small molecule and growth factor cocktail, including EGF, glycogen synthase kinase 3 inhibitor (CHIR99021), transforming growth factor β receptor inhibitor (e.g. E-616452), lysophosphatidic acid and sphingosine 1-phosphate, that can sustain long-term self-renewal of murine hepatoblasts under chemically defined conditions. The expandable hepatoblasts (eHBs) by this small molecule and growth factor cocktail expressed a set of genes typical of liver progenitor cells and liver development, and retained the ability to respond to liver developmental cues and produce functional hepatocytes and form bile duct-like structures. Moreover, both early- and late-passage eHBs demonstrated a similar transcriptome profile. Microarray analysis also confirmed that the gene expression of cultured cells resembled hepatoblasts.

Direct Reprogramming of Non-limb Fibroblasts to Cells with Properties of Limb Progenitors [scRNA-seq]

Project description:The early limb bud consists of mesenchymal progenitors (limb progenitors) derived from the lateral plate mesoderm (LPM) that produce most of the tissues of the mature limb bud. The LPM also gives rise to the mesodermal components of the trunk, flank and neck. However, the mesenchymal cells generated at these other axial levels cannot produce the variety of cell types found in the limb bud, nor can they be directed to form a patterned appendage-like structure, even when placed in the context of the signals responsible for organizing the limb bud. Here, by taking advantage of a direct reprogramming approach, we find a set of factors (Prdm16, Zbtb16, and Lin28) normally expressed in the early limb bud, that are capable of imparting limb progenitor-like properties to non-limb fibroblasts. Cells reprogrammed by these factors show similar gene expression profiles, and can differentiate into similar cell types, as endogenous limb progenitors. The further addition of Lin41 potentiates proliferation of the reprogrammed cells while suppressing differentiation. These results suggest that these same four key factors may play pivotal roles in the specification of endogenous limb progenitors.
