Figure 2. Thymosin β 4 immunoreactivity after 72 h of starvation.

Tβ 4 immunoreactivity in HepG2 cells cultured for 72 h with serum (A and B, magnification 1000×) and without serum (C and D, magnification respectively 400 and 1000×). Inserts in A and in C represent one particular of the intranuclear reactivity of the respective pictures (magnification 1000×).
