Aims And Background: The aims of this study were to investigate the correlation between topoisomerase II alpha (TOP2A), microtubule-associated protein-tau (MAP-tau) and other prognostic factors in breast cancer and to evaluate the predictive value of TOP2A and MAP-tau in breast cancer patients who received anthracycline and taxane-containing adjuvant chemotherapy.
Methods And Study Design: Seventy patients with axillary lymph node positive breast cancer who underwent curative surgery between January 2000 and December 2005 were evaluated retrospectively. The levels of protein expression of TOP2A and MAP-tau were assessed using immunohistochemistry.
Human mesenchymal stem cells (MSCs) communicate with other cells in the human body and appear to "home" to areas of injury in response to signals of cellular damage, known as homing signals. This review of the state of current research on homing of MSCs suggests that favorable cellular conditions and the in vivo environment facilitate and are required for the migration of MSCs to the site of insult or injury in vivo. We review the current understanding of MSC migration and discuss strategies for enhancing both the environmental and cellular conditions that give rise to effective homing of MSCs.

With the recent demonstration of MSC homing properties, intravenous applications of MSCs to cell-damaged diseases have increased. In the present study, the toxicity and tumorigenicity of human AdMSCs (hAdMSCs) were investigated for clinical application.

Here, we attempted the recloning of dogs by nuclear transfer of canine adipose tissue-derived mesenchymal stem cells (cAd-MSCs) from a transgenic cloned beagle to determine if cAd-MSCs can be a suitable donor cell type. In order to isolate cAd-MSCs, adipose tissues were collected from a transgenic cloned beagle produced by somatic cell nuclear transfer (SCNT) of canine fetal fibroblasts modified genetically with a red fluorescent protein (RFP) gene.
