The present invention relates to a method of inducing or improving wound healing properties of a mesenchymal stem cell population, the method comprising cultivating the mesenchymal stem cell population in a culture medium comprising DMEM (Dulbecco’s modified eagle medium), F12 (Ham’s F12 Medium), M171 (Medium 171) and FBS (Fetal Bovine Serum). The invention also relates to a mesenchymal stem population, wherein at least about 90 % or more cells of the stem cell population express each of the following markers: CD73, CD90 and CD105 and lack expression of the following markers: CD34, CD45 and HLA-DR. The invention also relates to a pharmaceutical composition of this mesenchymal stem population.本發明係有關一誘導或改善間質幹細胞群傷口癒合特性的方法，該方法包含將間質幹細胞群培養在含有DMEM (杜氏改良伊格爾培養基)、F12 (哈姆氏F12培養基)、M171 (培養基171)、及FBS (胎牛血清)的培養基中。本發明亦有關一間質幹細胞群，其中至少約90%或以上的幹細胞群細胞表現下列標記之每一者：CD73、CD90、及CD105，且缺乏下列標記之表現：CD34、CD45、及HLA-DR。本發明亦有關此間質幹細胞群之一藥學組成物。
