chicken chemokine can help heal wounds by inducing fibroblasts to become myofibroblasts, according to results reported by Feugate et al. on page 161. The contractile myofibroblasts help close the wound by pulling together the necessary cells and matrix. Chemokines are better known for their activities in the immune system, but increased production of chicken chemotactic and angiogenic factor (c...

Individuals with no/low RB protein expression were considered to have loss of RB function, and those with maximally phosphorylated (maxphos) RB were also felt to have nonfunctional RB. To confirm this, we prospectively investigated wheth...
