Abstract

The present invention provides a method for the in vitro culture of embryonic stem cells, wherein the stem cells continue to express no antigen or antigen CD117, and mostly remain undifferentiated during culture. The present invention also relates to purified preparations of embryonic stem cells and for uses of embryonic stem cells in treating a wide variety of conditions, diseases and disorders.

Claims

1. A method for improving athletic performance and increasing lean muscle mass in a patient, the method comprising the steps of:

administering hematopoietic stem cells to the patient via intravenous injection; and

administering neuronal stem cells to the patient via subcutaneous injection.

2. The method of claim 1, wherein about 10 million to about 100 million hematopoietic stem cells and about 10 million to about 80 million neuronal stem cells are administered to the patient.

3. The method of claim 1, wherein the hematopoietic stem cells and the neuronal stem cells are prepared by introducing embryonic stem cells into a chemically defined culture medium containing a growth factor, applying a microcurrent to the culture medium containing the stem cells, and incubating the culture medium containing the stem cells at a temperature from about 34°

C. to about 42°

C.

4. The method of claim 1, wherein the hematopoietic stem cells and the neuronal stem cells are extracted from a human embryo.
