Cell type - Wikipedia
WEBA cell type is a classification used to identify cells that share morphological or phenotypical features. [1] . A multicellular organism may contain cells of a number of widely differing and specialized cell types, such as muscle cells and skin cells, that differ both in appearance and function yet have identical genomic sequences.
