Maintenance of blastemal
proliferation by functionally diverse epidermis in regenerating zebrafish fins.
1] did not interfere in the expression of the genes required to the formation of the epidermal cap and the blastema, but could have interfered, momentarily, during transcriptions or translations or even complexing with proteins inhibiting their expression as an enzyme or structural functions as a protein in the process of blastemal
cells differentiation on the cells responsible for the synthesis and deposition of actinotrichia and lepidotrichia, or even in the necessary signalling to differentiated cells to trigger the synthesis of the components of the dermal skeleton.

The malignant elements differ from those seen in blastomas in that they lack the blastemal
primitive appearance and histologically resemble adult-type carcinomas and sarcomas.
On microscopy, multiple sections studied from the tumor showed admixture of blastemal
, epithelial and stromal components (Figure 3).
