However, the functional role of ENG during the transition of FLK1+ mesoderm to hematopoietic cells is ill defined.
However, the contribution of brain microvasculature and glial inflammatory activity to the recruitment of systemic, potentially neurotoxic, inflammatory cells remains ill defined (Allen et al., 2012).
The precise mechanism of molecular modulation of cell cycle arrest remains ill defined, but it is important to understand and to predict tumour cell response to statins.
Microscopic appearance of the tumor nodules was composed of monomorphic spindle cells arranged in ill defined fascicles and separated by slit like vessels containing erythrocytes.
TSPY expression is restricted to testicular tissue and its primary physiological function remains ill defined, but it may participate in germ cell proliferation and meiosis [ 74].
The structure and composition of P. infestans cell wall is still ill defined; however, it is clear that cellulose is one of its major components (as opposed to chitin, which is the major component of fungal cell walls [ 60]).
The chemotaxis of muscle stem cells to the site of injury is an ill defined, necessary component of the early response of satellite cells to myotrauma.
However, the molecular identity of the epithelial cells in the mammary primordia is still ill defined, and the degree of similarity to postnatal mammary epithelial cells remains largely unknown.
Skin biopsy showed ill defined granuloma formation with occasional multinucleate giant cells.
Selection criteria for cell-based models are often ill defined and arbitrary.
A significant proportion of CD4 and CD8 CD45RC T cell subsets contains two subpopulations with ill defined functions i.e; CD45RA+CD45RO−CCR7− and CD45RA+CD45RO+.
