Fig. 4From: Non-interfacial self-assembly of synthetic protocellsFabrication of artificial cancer cells via NISA method. (a) Schematic illustration of artificial cancer cell fabricated by NISA method. (b) The expression of CD44 mRNA was higher in A2780/PTX compared with its sensitive counterpart A2780 detected by qRT-PCR. (c) The expression of CD44 protein was higher in A2780/PTX compared with A2780 determined by Western blot. (d) Laser confocal micrograph of A2780 and A2780/PTX, CD44 protein was highly expressed in A2780/PTX analyzed by immunofluorescence. Scale bar, 5 μm. (e) Laser confocal micrograph of protocell A2780 and protocell A2780/PTX and the expression of CD44 protein was analyzed by immunofluorescence. Scale bar, 5 μmBack to article page
