Thank you doctor can be language translation in Arabic too. because many of us follow the channel but to understand because of the language. thank you very much
Hi Dr. Campbell. I always thoroughly enjoy your videos. You have been a source of inspiration to me. In my studies, there is one area I do not agree with you on, however. Stem cells in the stratum basale divide into two cells. One cell remains as an undifferentiated stem cell, while the other cell differentiates and becomes a part of the stratum spinosum. As a result, the number of stem cells never changes. Can you clarify this topic for me? (Source: Histology: A Text and Atlas by Pawlina 2016. 6th Ed.)
+Charles Forsythe Thanks Charles, interesting point, this would mean that all of the cells in the stratum basale at any one time are stem cells. Is this your understanding?
+Dr. John Campbell From Pawlina 'Histology' 6th Ed. page 489: The stratum basale is represented by a single layer of cells that rests on the basal lamina. In contains stem cells from which new cells, the keratinocytes, arise by mitotic division. For this reason, the stratum basale is also called the stratum germinativum.... As new keratinocytes arise in this layer by mitotic division, they move into the next layer, thus beginning their process of upward migration. Based on that, I believe that all the cells in the basal layer (besides Merkel's and melanocytes) are stem cells. What are your thoughts? Thanks too for the correspondence Dr. Campbell.
