- 1. A purified population of human fetal blood multi-lineage progenitor cells (MLPC), wherein said MLPC are positive for CD9, CD13, CD29, CD44, CD73, CD90 and CD105, and negative for CD10, CD34, CD41, CD45, Stro-1, Stage Specific Embryonic Antigen-3 (SSEA-3) and SSEA-4.
- 10. A clonal line of human fetal blood MLPC, wherein said MLPC are positive for CD9, CD13, CD29, CD44, CD73, CD90 and CD105, and negative for CD10, CD34, CD41, CD45, Stro-1, SSEA-3 and SSEA-4.

27. A purified population of MLPC, wherein said MLPC are made by the following method:
-
a) contacting a human fetal blood sample with a composition, said composition comprising; i) dextran; ii) anti-glycophorin A antibody; iii) anti-CD15 antibody; and iv) anti-CD9 antibody; b) allowing said sample to partition into an agglutinate and a supernatant phase; c) recovering cells from said supernatant phase; d) purifying MLPC from the recovered cells by adherence to a solid substrate; and e) culturing said MLPC such that said MLPC obtain a fibroblast morphology, wherein said MLPC, after obtaining said fibroblast morphology, are positive for CD9, CD13, CD29, CD44, CD73, CD90 and CD105, and negative for CD10, CD34, CD41, CD45, Stro-1, SSEA-3, and SSEA-4. - View Dependent Claims (28, 29, 30, 31)

32. A clonal line of MLPC, wherein said clonal line is made by the following method:
-
a) culturing a single MLPC in a culture vessel lacking other cells until a plurality of progeny are produced; and b) culturing said progeny to obtain said clonal line of MLPC, wherein said MLPC are positive for CD9, CD13, CD29, CD44, CD73, CD90 and CD105, and negative for CD10, CD34, CD41, CD45, Stro-1, SSEA-3, and SSEA-4. - View Dependent Claims (33, 34, 35, 36)
