- W2048385821 abstract "Reactive phosphorylcholine polymers, which can recognize biosynthetic cell-surface tags, were synthesized to control cell attachment. Human promyelocytic leukemia cells (HL-60) with unnatural carbohydrates as cell-surface tags were harvested by treatment with N-levulinoylmannosamine (ManLev). The attachment of ManLev-treated HL-60 cells to 2-methacryloyloxyethyl phosphorylcholine (MPC) polymers with hydrazide groups was studied. HL-60 cells, which are nonadhesive, did not attach to any polymer surface without ManLev treatment. In contrast, ManLev-treated HL-60 cells attached to a poly[MPC-co-n-butyl methacrylate (BMA)-co-methacryloyl hydrazide (MH)] (PMBH) surface following 15 min of incubation. The cells that attached to the PMBH surface retained their native morphology and viability for 24 h of incubation. On the other hand, approximately half of the HL-60 cells that attached to the poly(BMA-co-MH) (PBH) surface died. These results suggest that MH units in the polymer act as anchors for cell attachment and MPC units help to preserve cell viability on a polymer surface. The coculture of ManLev-treated HL-60 and fluorescence-stained human uterine cervical cancer cells (HeLa) was carried out on polymer surfaces. ManLev-treated HL-60 cells specifically attached to the PMBH surface. In contrast, both HL-60 and HeLa cells were observed on the PBH surface. The control of cellular interactions with synthetic polymers may be useful for the future development of cell-integrated biosensors and biomedical devices." @default.
