Human mesenchymal stem/progenitor cells (MSCs) have been identified in adult bone marrow, but little is known about their presence during fetal life. MSCs were isolated and characterized in first-trimester fetal blood, liver, and bone marrow. When 10 6 fetal blood nucleated cells (median gestational age, 10 +2 weeks [10 weeks, 2 days]) were cultured in 10% fetal bovine serum, the mean number (± SEM) of adherent fibroblastlike colonies was 8.2 ± 0.6/10 6 nucleated cells (69.6 ± 10/ μL fetal blood). Frequency declined with advancing gestation. Fetal blood MSCs could be expanded for at least 20 passages with a mean cumulative population doubling of 50.3 ± 4.5. In their undifferentiated state, fetal blood MSCs were CD29+, CD44 +, SH2 +, SH3 +, and SH4 +; produced prolyl-4-hydroxylase, α-smooth muscle actin, fibronectin, laminin, and vimentin; and were CD45 -, CD34 -, CD14 -, CD68 -, vWF -, and HLA-DR -. Fetal blood MSCs cultured in adipogenic, osteogenic, or chondrogenic media differentiated, respectively, into adipocytes, osteocytes, and chondrocytes. Fetal blood MSCs supported the proliferation and differentiation of cord blood CD34 + cells in longterm culture. MSCs were also detected in first-trimester fetal liver (11.3 ± 2.0/10 6 nucleated cells) and bone marrow (12.6 ± 3.6/10 6 nucleated cells). Their morphology, growth kinetics, and immunophenotype were comparable to those of fetal blood-derived MSCs and similarly differentiated along adipogenic, osteogenic, and chondrogenic lineages, even after sorting and expansion of a single mesenchymal cell. MSCs similar to those derived from adult bone marrow, fetal liver, and fetal bone marrow circulate in first-trimester human blood arid may provide novel targets for in utero cellular and gene therapy.
