OCTN1 protein in adult skin cells (a, b) and child skin cells (c, d),
The short arrow points to the basal cells and the long arrow points to the granular keratinocytes;
Compared with adult epidermis, OCTN1 expression in children’s skin was weaker in the basal layer and
stronger in the granular layer.
Note: Blue is the cell nucleus and green is the OCTN1 protein of the cell
