Postpartum cells derived from placental tissue, and methods of making and using the same
First Claim
1. A method of isolating a placenta-derived cell from a human postpartum placenta comprising dissociating said cell from said placenta with a matrix metalloprotease, a neutral protease, and a mucolytic enzyme that digests hyaluronic acid, wherein the isolated placenta-derived cell is obtained from human postpartum placenta substantially free of blood, and wherein the placenta-derived cell has the following characteristics:
- a) self-renews and expands in culture;
b) is multipotent;
c) produces CD10, CD13, CD44, CD73, CD90, PDGFr-alpha, PD-L2 and HLA-A,B,C;
d) does not produce CD31, CD34, CD45, CD80, CD86, CD117, CD141, CD178, B7-H2, HLA-G or HLA-DR-DP,DQ; and
e) expresses, relative to a human fibroblast, mesenchymal stem cell, or iliac crest bone marrow cell, increased levels of oxidized low density lipoprotein receptor 1 and renin.
