METHODS AND COMPOSITIONS FOR EX VIVO GENERATION OF DEVELOPMENTALLY COMPETENT EGGS FROM GERM LINE CELLS USING AUTOLOGOUS CELL SYSTEMS

摘要

The present technology provides for methods for the directed differentiation of multi-potent cells, female germ line stem cells, or oogonial stem cells into oocytes, granulosa cells and/or granulosa precursor cells, i.e.,“synthetic granulosa cells.” The synthetic granulosa cells are useful in methods for growth and maturation of follicles or follicle-like structures and immature oocytes. Additionally, the synthetic granulosa cells are useful in methods of increasing ovarian derived hormones and growth factors in a subject in need thereof.
