Lifecycle of the Keratinocyte

EXCELLENT...........

[@guytelfer1353]

So the kerotinsyte are centromeres or centrisomes

tq for vudeo awsome 🤗

Does anyone know the growth rate of primary gingival keratinocytes?

[@Pastiche-Training]

If it's a similar process, then it should be quicker than that of the epidermis as there is no final cornification stage.

nice video

Thanks

No mention of keratohyalin or tonofibrils?

[@Pastiche-Training]

Thanks for your comment. The detail of keratohyalin and tonofibrils are beyond the scope of this short video, (It covers the fundamentals) but are reviewed in some of our training courses.

Hi. I was wondering the same thing too and actually i was looking for such an information on the internet cause my histology book does not refer further to that. What i have understood till now is that granules with keratohyalin that are stored in ribosomes get dispersed in the cytoplasm (once in the granular layer) and they help the filaments of keratohyalin to group and form the tonofibrils even further than it was happening in the previous layers of the epidermis. The nucleus and other organeles are broken down too and , thus , the keratinocells are fulled with only tonofibrils in the keratin layer. If you have found more information about that, i would be thankful if you could share your source :)

@@fedonable Tonofibrils are cytoplasmic protein structures in epithelial tissues that converge at desmosomes and hemidesmosomes. They consist of fine fibrils in epithelial cells that are anchored to the cytoskeleton.
