Cardiac stem cells

A biopsy forceps (1) comprises a flexible pipe (2) which can be remotely controlled. Two handles (6 and 7) which are connected to the near end of the pipe are used for operating a pair of clamps (4 and 5) that are connected to the far end of the pipe. An independent control handle (8) comprises a rotatable knob (16). The knob rotates in the reverse direction to facilitate the bending of the pipe in the second direction. A control knob can be connected to the far end of the pipe through the operating lines (42 and 43) that moves in the cavities (44 and 45) of the pipe in company with the rotation of the knob. The clamps (or other control component) at the far end of the pipe are replaceable (80A and 80B).

Method for separating heart stem cells from brown fat and splitting cardioblast

The invention discloses a method for separating heart stem cells from brown fat and splitting cardioblast. The method comprises the following steps: (1) preparing digestive juice: dissolving callagenase, dispase II and pancreatin in the mass ratio of 1:1:0.5-1 in a serum-free culture medium; (2) digesting the brown fat tissue with a digestion bottle added with glass beads and rotors, and then centrifugally collecting the cells; and (3) cultivating the progenitor heart stem cells and splitting the cardioblast. By adopting the combined digestive enzyme liquid and a special digestion method for cell separation, the separation method remarkable improves the yield of cells and the content of heart stem cells compared with the existing separation method, and remarkably improves the yield of the heart stem cells by verifying the expression rate of CD133 and the capability of the cardioblast. By using the method, the yield of the obtained heart stem cells is high, the operation is simple, the implementability is strong and the manual operation is reduced.

Method to amplify cardiac stem cells in vitro and in vivo

Compositions comprising stem cells delivered into infarcted myocardium by endocardial injection, engraft and differentiate into myocytes, endothelial cells, and vascular smooth muscle, and do so without the requirement for survival enhancing modification. These cells engraft whether injected acutely (days) or late (months) after myocardial infarction, and the efficiency of engraftment correlates with the functional recovery of the heart. The stem cells also recruit endogenous cardiac precursor cells, reconstitute myocardial stem cell niches, and enhance endogenous cell differentiation into myocytes.
