However, the promise of keratinocyte stem cells seems slim for generating nonepidermal tissues. Using our recently developed acclimatization induction strategy, we demonstrate the multipotency of adult human undifferentiated keratinocytes (UKs). The UKs were isolated from the basal layer of adult human foreskin and cultured in Epilife medium, which allows for the growth of only keratin-positive keratinocytes, promotes high proliferation of UKs, and prevents their differentiation. Induction of the UKs by either serum or lineage-committed medium only produce differentiated epidermal cells. Hence, serum or lineage-committed medium was added to Epilife to acclimate UKs to differentiate to other cell types. Unexpectedly, serum acclimatization can induce UKs to produce a large number of smooth muscle cells and fewer of adipocytes and neurocytes within 3 weeks. In contrast, except for the terminally differentiated epidermal cells, committed acclimatization can induce UKs to differentiate exclusively into the adipocytic, myogenic, or neurogenic lineages. These data indicate that human UKs represent a novel multipotent adult stem cell, and suggest that they may provide an accessible, therapeutically promising cell source for regenerative medicine.<\/jats:p>","DOI":"10.1089\/cell.2009.0095","type":"journal-article","created":{"date-parts":[[2010,6,30]],"date-time":"2010-06-30T23:04:44Z","timestamp":1277939084000},"page":"283-294","source":"Crossref","is-referenced-by-count":5,"title":["Acclimatized Induction Reveals the Multipotency of Adult Human Undifferentiated Keratinocytes"],"prefix":"10.1177","volume":"12","author":[{"given":"Weidong","family":"Han","sequence":"first","affiliation":[{"name":"Institute of Basic Medical Science","place":["People's Republic of China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Meixia","family":"Chen","sequence":"additional","affiliation":[{"name":"Institute of Basic Medical Science","place":["People's Republic of China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Meirong","family":"Li","sequence":"additional","affiliation":[{"name":"Institute of Basic Medical Science","place":["People's Republic of China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhiqiang","family":"Wu","sequence":"additional","affiliation":[{"name":"Institute of Basic Medical Science","place":["People's Republic of China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yali","family":"Zhao","sequence":"additional","affiliation":[{"name":"Institute of Basic Medical Science","place":["People's Republic of China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yao","family":"Wang","sequence":"additional","affiliation":[{"name":"Institute of Basic Medical Science","place":["People's Republic of China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lili","family":"Wang","sequence":"additional","affiliation":[{"name":"Chinese PLA General Hospital","place":["People's Republic of China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Li","family":"Yu","sequence":"additional","affiliation":[{"name":"Chinese PLA General Hospital","place":["People's Republic of China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaobing","family":"Fu","sequence":"additional","affiliation":[{"name":"Institute of Basic Medical Science","place":["People's Republic of China"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2010,6,30]]},"reference":[{"key":"e_1_3_3_2_1","doi-asserted-by":"publisher","DOI":"10.1038\/nbt.1503"},{"key":"e_1_3_3_3_1","doi-asserted-by":"publisher","DOI":"10.1038\/nature02069"},{"key":"e_1_3_3_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/dvdy.21330"},{"key":"e_1_3_3_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.stem.2008.06.011"},{"key":"e_1_3_3_6_1","doi-asserted-by":"publisher","DOI":"10.1038\/75705"},{"key":"e_1_3_3_7_1","doi-asserted-by":"publisher","DOI":"10.1038\/nrm2636"},{"key":"e_1_3_3_8_1","doi-asserted-by":"publisher","DOI":"10.1038\/nature06965"},{"key":"e_1_3_3_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.expneurol.2007.09.002"},{"key":"e_1_3_3_10_1","doi-asserted-by":"publisher","DOI":"10.1096\/fj.06-5880com"},{"key":"e_1_3_3_11_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.309.5731.84"},{"key":"e_1_3_3_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cellbi.2007.01.007"},{"key":"e_1_3_3_13_1","doi-asserted-by":"publisher","DOI":"10.1038\/nature05659"},{"key":"e_1_3_3_14_1","doi-asserted-by":"publisher","DOI":"10.1101\/gad.1645908"},{"key":"e_1_3_3_15_1","first-page":"114","article-title":"Flow cytometry of human primary epidermal and follicular keratinocytes","volume":"8","author":"Gragnani A.","year":"2008","unstructured":"Gragnani A., , Ipolito M.Z., , Sobral C.S. et al. 2008.
