Furthermore, in fetal ovaries, NTF4 could potentially promote human follicular assembly.29 Because prostate cancer tends to invade neural tissue, NTF4 has also been studied in and stained ductal cells.30 NTF4 could stimulate cell proliferation and migration through its receptor both in melanoma and O‐2A cells.31, 32. The gene discussed is NTF4; the disease is melanoma.
