As expected, the bone marrow was chosen as the source of hMSCs in the majority of the articles analyzed. A total of 69 out of the 132 articles selected isolated hMSCs from the bone marrow (35, 37, 42–45, 47, 49–58, 60, 62–64, 66–73, 77, 79, 80, 92, 95, 98, 99, 102, 107, 108, 110, 111, 115–118, 122, 123, 125–128, 131, 132, 133, 134, 135, 137, 138, 143, 146, 148–150, 154–158, 161). In addition, other common sources of hMSCs included the umbilical cord blood or stroma [29 articles (36, 38, 39, 41, 46, 61, 65, 75, 76, 78, 82, 85, 89, 91, 93, 95, 97, 100, 101, 103, 107, 113, 119, 124, 128, 142, 144, 155, 158)] and the adipose tissue [27 articles (40, 59, 74, 83, 86, 87, 94, 96, 100, 103, 104, 106, 110, 120, 121, 128, 130, 136, 140, 141, 145, 151–153, 156, 158, 159)]. On the other hand, the dental pulp was chosen as the source of hMSCs in only five articles (33, 84, 114, 147, 162), in two articles hMSCs were isolated from the gingiva (90, 99), in two articles hMSCs were obtained from the menstrual blood (72, 105) and in five articles (34, 48, 88, 129, 139) hMSCs were isolated from extra embryonic membranes such as the placenta and fetal membrane. Finally, in six studies (81, 102, 103, 137, 157, 160) hMSCs were obtained from the directed differentiation of embryonic stem cells. The sources of hMSCs used for the isolation of hMSCs in the articles reviewed are graphically represented on Figure 3.
