COMPOSITION AND METHOD FOR GENERATING A DESIRED CELL TYPE AND/OR TISSUE TYPE FROM HAIR FOLLICULAR STEM CELLS
The present invention is concerned with a composition and in vitro method for generating a desired cell type and/or tissue type from hair follicular stem cells. The composition and in vitro method are particularly suitable for generating an autologous desired cell type and/or tissue type. Furthermore, the composition and method are especially efficient and suitable for use in the context of cosmetic cell and/or tissue transplantation in recipient areas of a subject experiencing cell and/or tissue loss caused by, for example, a wound, scar, burn injury, tissue degeneration, and aging. The composition and in vitro method are also suitable to circumvent complications related to infections and/or immune rejection of a cosmetic cell and/or tissue implant or graft.
METHODS FOR OBTAINING INDUCED PLURIPOTENT STEM CELLS
Provided herein are methods of obtaining induced pluripotent stem cells from cells of a hematopoietic lineage.
Serum-free complete medium for inducing differentiation of a mesenchymal stem cell to a corneal epithelial cell
A serum-free complete medium for inducing differentiation of a mesenchymal stem cell to a corneal epithelial cell in the field of differentiation induction of stem cells, prepared by the following method: uniformly mixing the serum-free complete medium, containing 5-10 ?mol of resveratrol, 2-4 ?mol of icariin, 1-3 nmol of aspirin, 1-3 nmol of parathyroid hormone, 5-10 nmol of hydrocortisone, 1-3 mg of rapamycin, 2-10 ?g of testosterone, 2-10 ?g of EPO, 2-10 ?g of LIF and the balance of a corneal epithelial cell serum-free medium in per 1 L; and then performing sterilization by filtration. The disclosure uses resveratrol and icariin in combination with aspirin, parathyroid hormone, hydrocortisone, rapamycin, testosterone and growth factors to cooperatively induce directional differentiation, uses nontoxic induction components, is high in induction efficiency and short in induction time, and achieves high induced corneal epithelial cell activity, no cell transplantation rejection, no ethical problem and high safety.
Inducer for inducing a mesenchymal stem cell to differentiate into an islet cell
The present invention belongs to the field of biomedicine, and relates to an inducer for inducing a mesenchymal stem cell to differentiate into an islet cell. An inducer for inducing a mesenchymal stem cell to differentiate into an islet cell consisted of the following components: GLP-1, parathyroid hormone, paracetamol, rapamycin, icariin, trametinib, EPO and VEGF. Each component in a inducer for inducing a mesenchymal stem cell to differentiate into an islet cell of the present invention is safe and non-toxic, requiring fewer steps and short time to induce differentiation, with high induction efficiency.
Method for the isolation of subpopulations of cardiac progenitor cells and related uses in the medical field
The present invention relates to a method for the isolation of subpopulations of cardiac progenitor cells from a heart tissue sample, the population thus obtained and the related uses in the medical field for the cell therapy or cardiac cell and/or tissue transplantation field.
HAEMATOPOIETIC STEM/PROGENITOR CELLS
The invention relates to an isolated cell having, after culturing a pluripotent stem cell (PSC) in a medium comprising a WNT agonist and an ACTIVIN antagonist, increased HOXA gene expression relative to a PSC not cultured in a medium comprising a WNT agonist and an ACTIVIN antagonist, wherein the cell with increased HOXA gene expression is capable of generating a definitive haematopoietic stem/precursor cell. The invention also relates to use of the cell for generating a definitive haematopoietic stem/precursor cell, and a method for differentiating a PSC into a definitive haematopoietic stem/precursor cell and a definitive haematopoietic stem/progenitor cell differentiated from a PSC by the method. The invention further relates to a therapeutic composition comprising a cell of the invention, and to therapeutic methods and uses of a cell of the invention. The invention also relates to a reporter cell comprising distinguishable SOX 7 and RUNXIC reporters, for use in tracking the differentiation of a PSC into a definitive haematopoietic stem/progenitor cell.
Production and use of red blood cells
The present disclosure relates to the production of red blood cells from hematopoietic stem cells, by differentiating such cells in the presence of a protein that induces cell survival and proliferation.
In vitro expansion of erythroid cells
The present invention relates to a method for in vitro expansion of erythroid cells. The method includes subjecting erythroid cells to 3-dimensional packed cell culture using a porous structure. The use of the composition according to the present invention enables in vitro expansion of erythroid cells in the most efficient manner.
Induction medium and methods for stem cell culture and therapy
Novel MSC stem-cell culture and therapy methods and culture medium compositions for the purpose of inducing, activating, or priming discrete uniform cell phenotypes to selectively promote or suppress inflammation and immunity, yielding polarized, primed, activated, or induced cells used in cell-based therapy.
Human extensively self-renewing erythroblasts (ESRE)
The present invention provides a human cell population that can self-renew extensively and yet retain the capacity to differentiate into red blood cells (RBCs). These cells are referred to as extensively self-renewing erythroblasts (ESREs). The cells of the invention serve among other things as a renewable source of transfusable RBCs.
