positively regulates positively regulates cell morphogenesis involved in differentiation positive regulation of cell development regulation of cell morphogenesis involved in differentiation positive regulation of cell morphogenesis involved in differentiation biological_process Any process that increases the frequency, rate or extent of cell morphogenesis contributing to cell differentiation. Cell morphogenesis involved in differentiation is the change in form (cell shape and size) that occurs when relatively unspecialized cells acquire specialized structural and/or functional features that characterize the cells, tissues, or organs of the mature organism or some other relatively stable phase of the organism's life history.
