Abstract
The invention discloses a substantially pure population of human ovarian mesothelial cells and methods of isolating and culturing the ovarian mesothelial cells. By carefully manipulating the microenvironment of the ovarian mesothelial cells, multiple passages are attainable wherein the ovarian mesothelial cells are capable of becoming ovary surface epithelial cells or granulosa cells. In addition, several methods of use of human ovarian mesothelial cells are disclosed herein.
Claims13
A substantially pure population of human ovarian mesothelial cells wherein said ovarian mesothelial cells have a pluripotent capacity to differentiate into ovary surface epithelial cell or granulosa cells.
A method of isolating a substantially pure population of ovarian mesothelial cells, comprising:
- (a) microdissecting a source of human fetal ovarian mesothelial cells;
- (b) placing the source of ovarian mesothelial cells in nutrient media under culture conditions sufficient to sustain life of said ovarian mesothelial cells and wherein the nutrient media contains nutrients consisting of insulin, transferrin, epidermal growth factor, α-tocopherol, recombinant human heregulin β1, bovine serum albumin, and aprotinin;
- (c) maintaining suitable culture conditions sufficient to allow the migration of ovarian mesothelial cells from the source of ovarian mesothelial cells into the nutrient media;
- (d) maintaining suitable culture conditions sufficient to allow ovarian mesothelial cells to form aggregate or monolayer formations;
- and
- (e) subculturing said aggregate or monolayer formations to obtain a substantially pure population of ovarian mesothelial cells.
