Growth of neural precursor cells using umbilical cord blood serum and a process for the preparation thereof for therapeutic purposes

Abstract

This invention is concerned with stem cells derived from umbilical cord blood serum and a method for growing human embryonic stem cells and adult cells comprising sera separated from clotted umbilical cord blood, including growing and differentiating cord blood stem cells into neural precursors, comprising transdifferentiating CD34+ stem cells from mononuclear cells derived from umbilical cord blood to neural precursors. The stem cells obtained from the umbilical cord include pluripotent stem and progenitor cell population of mononuclear cells, and separating pluripotent stem and progenitor cell population of mononuclear cells obtained from the umbilical cord blood. A magnetic cell separator is used to separate out cells which contain a CD marker and then expanding the cells in a growth medium containing retinoic acid and one or more growth factors BDNF, GDNF, NGF and FGF as a differentiating agent. The invention is also concerned with the transplantation and repair of nerve damage, stokes, spinal injury, Parkinson's and Alzheimer's, prepared in accordance with the aforesaid method and a media for culturing umbilical cord blood stem calls consisting essentially of cord blood stem cells derived from umbilical cord blood serum.
