Abstract
Official abstract text for this publication.
An object of the present invention is to provide stem cells having excellent proliferation ability and differentiation ability. The present invention relates to stem cells isolated from a neonatal pig, and a preparation method therefor.
First claim
Opening claim text (preview).
1 . Stem cells isolated from a neonatal pig. 2 . The stem cells according to claim 1 , wherein an average diameter is 17 μm or less. 3 . The stem cells according to claim 1 , wherein a doubling time in a logarithmic growth phase is 36 hours or less. 4 . The stem cells according to claim 1 , wherein the stem cells are mesenchymal stem cells. 5 . The stem cells according to claim 1 , wherein the neonatal pig is a neonatal pig that enables cell transplantation into a human. 6 . The stem cells according to claim 1 , wherein the stem cells are isolated from the bone marrow or the pancreatic islet of the neonatal pig. 7 . The stem cells according to claim 1 , wherein the stem cells are stem cells for transplantation. 8 . The stem cells according to claim 7 , wherein the stem cells are stem cells for human transplantation. 9 . The stem cells according to claim 1 , wherein the stem cells are stem cells for feeder cells. 10 . The stem cells according to claim 9 , wherein the stem cells are stem cells for feeder cells for proliferating stem cells for human transplantation. 11 . A method for preparing stem cells, comprising a step of isolating cells from a neonatal pig. 12 . The method for preparing stem cells according to claim 11 , comprising a step of subculturing the stem cells after 3 to 12 days from inoculation. 13 . The method for preparing stem cells according to claim 11 , wherein the cells to be isolated from the neonatal pig are cells in a monocytic cell fraction. 14 . The method for preparing stem cells according to claim 11 , wherein the isolation of the cells from the neonatal pig is isolation of the cells from the bone marrow or the pancreatic islet of the neonatal pig. 15 . The method for preparing stem cells according to claim 13 , comprising a step of freezing the isolated cells in the monocytic cell fraction.
