Haptoglobin, a protein induced by obesity, attracts monocytes through an interaction with the chemokine receptor CCR2, and could therefore mediate the infiltration of these inflammatory cells into adipose tissue where haptoglobulin is upregulated.

A changing proteomic profile accompanies blastema formation in an amputated axolotl limb, providing insight into the dedifferentiation and reprogramming of this mass of cells as they prepare for limb regeneration.

A high throughput 3-D culture system succeeds in establishing glandular acini from a human mammary epithelial cell line, and demonstrates the importance of basal polarity-mediated signals and collagen IV in recapitulating apical polarity.
