Growing fractions of both HC and cytokine-conditioned NPCs were also determined by the expression of the Ki67 antigen, which is expressed exclusively in proliferating cells during the late G1, S, G2 or M phase of the cell cycle.
These modes are determined by the expression levels of an intrinsic membrane conductance, an inwardly rectifying potassium current (IKir).
In vitro studies also demonstrated that 20/80 HA/TCP stimulated the osteogenic differentiation of hMSCs as determined by the expression of osteocalcin.
The host range of poliovirus is determined by the expression of the hPVR, a member of the immunoglobulin superfamily.
Reactivity was measured by aggregation (5 and 20 microM ADP) and activation was determined by the expression of total and active GP IIb/IIIa.
Denote by K an operator determined by the expression [Kf ] (x )= int_{0}^{x}K (x,t )f (t ),dt.
This condition is determined by the expression (2) and must be fulfilled for a specific time period given by the Time To Trigger (TTT) parameter.
From an understanding of the molecular nature of Hd3a/FT proteins, it can be inferred that the timing of rice flowering is basically determined by the expression levels of the two essential flowering promotion genes, Hd3a and RFT1 in leaf blades, and by the competency of the SAM for Hd3a/FT activity.
The folds of expression for each gene in cells treated with the drug relative to control treated cells is determined by the expression: 2−ΔΔCT.
In addition it may suggest a modular mode of action, where the level of activity is determined by the expression of Bmi1, and the relative levels of the other RING-domain subunits influence the target selectivity.
