But it has been recently shown than the behavior of melanocytes can be modified by manipulating keratinocytes which do not have any pigment of their own.Anonymoushttps://www.blogger.com/profile/11697985789503833415noreply@blogger.comtag:blogger.com,1999:blog-5995754777906978314.post-60798494677543700902013-01-27T09:40:00.656-08:002013-01-27T09:40:00.656-08:00Teech,
