We cultured MKs on tissue-culture treated (TC) and Ultra Low Attachment (ULA) surfaces.
We examined changes in MK polyploidization and proplatelet formation (PPF).
CHRF cells displayed increased polyploidization and arrested PPF on a ULA surface.
ULA culture did not affect primary MK polyploidization, but decreased PPF.
Primary MKs and CHRF cells showed rapid PPF after transfer from a ULA to a TC surface.
