High-Resolution Imaging and Antitumor Effects of GFP+ Bone Marrow-Derived Cells Homing to Syngeneic Mouse Colon Tumors
Investigators have established a mouse model for imaging bone marrow-derived cells from whole tumor to single-cell resolution, whereby the bone marrow of lethally irradiated host animals is reconstituted with EGFP-expressing bone marrow cells from matched TgActb(EGFP) donors. [Am J Pathol]
Abstract | Press Release

Reprogramming within Hours Following Nuclear Transfer into Mouse but Not Human Zygotes
Using fertilized eggs, investigators found that when the zygotic genome was replaced with that of a somatic cell, development progressed normally throughout the cleavage stages, but then arrested before the morula stage. [Nat Commun]
