USE OF CELLS DERIVED FROM FIRST TRIMESTER UMBILICAL CORD TISSUE
20210246420 · 2021-08-12 ·

A method of isolating a pluripotent cell from human umbilical cord is described herein. Cells so isolated may be reprogrammed as pluripotent cells and differentiated for use in cardiovascular treatment, may be used in screening cardiovascular drug candidates, or may be used in cell-based and cell-free therapy for inflammatory conditions. The method involves collecting a sample of umbilical cord from fetal tissue obtained at less than 13 weeks of gestation, for example a first trimester umbilical cord. The sample is treated to obtain isolated umbilical cord cells, after which the isolated umbilical cord cells are incubated. Cells obtained in this way can be differentiated for use in treating conditions of cell damage, by supplanting the function of a damaged cell in a condition such as spinal cord injury, cardiovascular injury or heart disease.

Composition and method for generating a desired cell type and/or tissue type from hair follicular stem cells
11840706 · 2023-12-12 ·

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.
