Abstract
The present invention relates to female germline stem cells and their progenitors, methods of isolation thereof, and methods of use thereof.
Claims
exact text as granted — not AI-modifiedWe claim:
1 . An isolated population of mitotically active non-embryonic stem cells expressing Vasa, Oct-4, Dazl, Stella and optionally a stage-specific embryonic antigen prepared by a process comprising selecting cells in a sample of mammalian ovarian tissue based on expression of a first genetic marker selected from a stage-specific embryonic antigen, Vasa, Oct-4, Dazl or Stella.
2 . The isolated population of claim 1 , wherein the mammalian ovarian tissue is human ovarian tissue.
3 . The isolated population of claim 1 , wherein the first genetic marker is a stage-specific embryonic antigen.
4 . The isolated population of claim 1 , wherein the first genetic marker is Vasa.
5 . The isolated population of claim 1 , wherein the first genetic marker is Oct-4.
6 . The isolated population of claim 1 , wherein the first genetic marker is Dazl.
7 . The isolated population of claim 1 , wherein the first genetic marker is Stella.
8 . The isolated population of claim 1 , wherein selecting cells based on the first genetic marker comprises selecting mRNA or protein corresponding to the first genetic marker.
9 . The isolated population of claim 1 , wherein selecting cells based on the first genetic marker comprises fluorescence activated cell sorting (FACS).
10 . The isolated population of claim 1 , wherein the process further comprises culturing the selected cells.
11 . A cell preparation comprising the isolated population of claim 1 and a pharmaceutically acceptable carrier.
12 . The isolated population of claim 1 , wherein the cells are further selected based on expression of a second genetic marker selected from a stage-specific embryonic antigen, Vasa, Oct-4, Dazl or Stella, wherein the second genetic marker is different from the first genetic marker.
13 . The isolated population of claim 12 , wherein the second genetic marker is a stage-specific embryonic antigen.
14 . The isolated population of claim 12 , wherein the second genetic marker is Vasa.
15 . The isolated population of claim 12 , wherein the second genetic marker is Oct-4.
16 . The isolated population of claim 12 , wherein the second genetic marker is Dazl.
17 . The isolated population of claim 12 , wherein the second genetic marker is Stella.
18 . The isolated population of claim 12 , wherein selecting cells based on the second genetic marker comprises selecting mRNA or protein corresponding to the second genetic marker.
19 . The isolated population of claim 12 , wherein selecting cells based on the second genetic marker comprises fluorescence activated cell sorting (FACS).
20 . The isolated population of claim 12 , wherein the process further comprises culturing the selected cells.
21 . A composition comprising a cell preparation of isolated non-embryonic stem cells that are mitotically competent and express Vasa, Oct-4, Dazl, Stella and optionally a stage-specific embryonic antigen, wherein the non-embryonic stem cells are isolated from mammalian ovarian tissue.
22 . The composition of claim 21 , wherein the non-embryonic stem cells are female germline cells.
23 . The composition of claim 21 , wherein the non-embryonic stem cells are isolated from human ovarian tissue.
24 . The composition of claim 21 , wherein the expression of one or more of Vasa, Oct-4, Dazl, Stella or a stage specific antigen is determined by detecting mRNA, protein, or a combination thereof.
25 . The composition of claim 21 , wherein the cells are isolated by a process comprising fluorescence activated cell sorting.
26 . The composition of claim 21 , further comprising cell culture medium.
27 . The composition of claim 21 , further comprising a pharmaceutically acceptable carrier.
28 . The composition of claim 21 , wherein the non-embryonic stem cells are cultured.
29 . The composition of claim 28 , further comprising cell culture medium.
30 . The composition of claim 28 , further comprising a pharmaceutically acceptable carrier.Join the waitlist — get patent alerts
