Cardiac stem cells therapy for myocardial infarction using novel hydrogel

将gfp阳性大鼠心脏干细胞偶联成热敏新型水凝胶（Hg），注射到心肌梗死大鼠心脏。在第四周时，与单独使用细胞的大鼠相比，使用水凝胶的大鼠的心脏功能得到了更大的改善。组织学分析表明，水凝胶组注射的细胞保留更多，心脏标志物和血管标志物蛋白的表达增加。

Cardiac stem cells derived from GFP-positive rat heart were conjugated into thermo sensitive novel hydrogel (Hg), then injected into the rat hearts with myocardial infarction. Greater improvement of heart function was seen in the rat with hydrogel administration compared to the rat with cells alone at four weeks. Histological analysis demonstrated that the injected cells were more retained in the hydrogel group, with increasing expression of cardiac marker and vascular marker proteins in the heart.
