A homogeneous population of cells derived from umbilical cord tissue, for use in the treatment of a degenerative eye condition, where said population can be obtained by enzymatic digestion of blood-free umbilical cord tissue by using enzymatic activities of matrix matrices. metalloproteases, neural proteases and mucolytic enzymes, and where this cell population is capable of self-renewing and expanding in cultures, has the potential to differentiate into cells of other phenotypes, and when the cell population: (a) produces each of CD10 , CD13, CD44, CD73, CD90, PDGFr-alpha and HLA-A, B, C, detected by flow cytometry; and (b) produce no CD31, CD34, CD45, CD117, CD141 and HLA-DR, DP, DQ, as detected by flow cytometry. |
