Chemical Reprogramming of Human T Cells to Pluripotent Stem Cells

ABSTRACT: Chemical reprogramming provides an innovative approach to convert somatic cells into pluripotent state using small molecules, holding great promise for regenerative medicine. Since the successful generation of human chemically induced pluripotent stem (hCiPS) cells in 2022, this strategy has emerged as a powerful tool for inducing pluripotency in diverse cell types. However, whether terminally differentiated somatic cells with stable identities, such as T cells, could be chemically reprogrammed toward pluripotency, remains unknown. Here, we adapted a chemical reprogramming method to successfully reprogram CD3+ and CD8+ T lymphocytes into hCiPS (hT-CiPS) cells. These cells fulfilled characteristics of human pluripotent stem cells, and TCR rearrangements analysis confirmed their T cell origin. Moreover, hT-CiPS cells can efficiently generate TCR-expressing cells and re-differentiate to CD4/CD8 positive T cells. Our findings reveal that chemical reprogramming can effectively convert terminally differentiated cells into pluripotent cells, holding promise for clinical applications in immunotherapy and regenerative medicine.

Chemical Reprogramming of Human Blood Cells to Pluripotency under Serum-Free Conditions

Project description:Small molecule-based chemical reprogramming provides a fundamentally innovative approach for generating human chemically induced pluripotent stem cell. Our recent work has successfully applied this chemical strategy to efficiently reprogram human blood cells to pluripotency. However, the absence of serum-free conditions for blood cell reprogramming significantly limited the further clinical translation. Here, we established a robust and defined serum-free condition that enable the stable reprogramming of human blood cells into hCiPS cells. This method has been reliably reproduced across over 10 different donors and can generate hCiPS cells within 20 days. The serum-free blood derived-hCiPS cells exhibit typical characteristics of human pluripotent stem cells. Furthermore, this approach allows for efficient generation of hCiPS cells even from a small volume of fingerstick blood. In summary, this study established a powerful and defined conditions for deriving hCiPS cells from blood cells, thereby greatly facilitating their further clinical applications in regenerative medicine.

Chemical reprogramming of human blood cells into hCiPS cells [bulk RNA-seq]

Project description:Chemical reprogramming offers a fundamentally innovative approach for generating human pluripotent stem (hCiPS) cells using small molecules. Our recent studies showed that this approach was highly efficient in reprogramming human fibroblasts to hCiPS cells. In this study, we established a robust method that successfully generated hCiPS cells from both cord blood and adult peripheral blood cells. This method achieved efficient reprogramming with both fresh and cryopreserved blood cells.

A XEN-like state bridges somatic cells to pluripotency during chemical reprogramming

Project description:Pluripotent stem cells can be generated from somatic cells by using pure chemicals.However, the cell fate dynamics and molecular events that occur during the chemical reprogramming process remain unclear. In this study, we found that the chemical reprogramming process requires the early formation of extra-embryonic endoderm (XEN)-like cells and a late transition from XEN-like cells to CiPSCs, a new route that differs from the pathway of transcription factor-induced reprogramming. Moreover, by more precisely manipulating the cell fate transition in a step-wise manner through the XEN-like state, we identified small-molecule boosters and established a robust chemical reprogramming system, with a yield up to 1,000-fold greater than that of the previously reported protocol. These findings demonstrate that chemical reprogramming is a unique and promising approach in the future manipulation of cell fates. We analyzed the gene expression profiles of intermediate cells obtained from diferent timepoints during chemical reprogramming process,using RNA-Sequencing. Embryo-derived XEN cells (eXENs), chemically-derived eXEN cell lines (CeXENs), embryonic stem cells (ESCs) and chemically-induced pluripotent stem cells (CiPSCs) are used as controls.

Pluripotent Stem Cells Induced from Mouse Neural Stem Cells and Small Intestinal Epithelial Cells by Small Molecule Compounds

Project description:Pluripotent stem cells can be generated by pure small molecule compounds. However, only fibroblasts, a heterogeneous cell population, were reported for use in chemical reprogramming, and the efficiency is relatively low, raising the possibility that chemically induced pluripotent stem cells (CiPSCs) are derived from a specific cell subpopulation residing in fibroblast culture. Thus, it is of interest to know whether chemical reprogramming can be induced in other cell types, even using the same chemical cocktail. Here, using lineage tracing, we verify the generation of CiPSCs from fibroblasts. We further demonstrate that neural stem cells (NSCs) and small intestinal epithelial cells (IECs), cell types from the ectoderm and endoderm, respectively, can be chemically reprogrammed into pluripotent stem cells. CiPSCs derived from NSCs and IECs resemble mouse embryonic stem cells (ESCs) in terms of proliferation rate, global gene expression profiling, epigenetic status, self-renewal and differentiation capacity, and germline transmission competency. Interestingly, in the chemical reprogramming process from different cell types, a pluripotency gene Sall4 was commonly expressed in the initial stage, and the same core small molecules were required, suggesting conservatism underlying chemical reprogramming from different cell types. Moreover, the use of these small molecules should be fine-tuned to meet the requirement of reprogramming from different cell types. Together, these findings demonstrate that our reported chemical reprogramming approach can be reproduced in different cell types and suggest that chemical reprogramming is a promising strategy with the potential to be extended to more initial cell types. We analyzed the gene expression profiles of NSC-derived CiPSCs and IEC-derived CiPSCs ,using RNA-Sequencing. NSCs, IECs, and embryonic stem cells (R1) are controls.
