科学领域:
- 再生医学是一种再生医学.
- 伤口治愈研究研究 伤口治愈研究
- 糖尿病并发症 糖尿病并发症
背景情况:
- 人类骨髓衍生中干细胞 (hBM-MSCs) 具有重要的分化和增殖能力,对于组织修复至关重要.
- 糖尿病患者经常表现出受损的伤口愈合,特别是在烧伤中,需要新的治疗策略.
研究的目的:
- 调查hBM-MSCs在糖尿病老鼠烧伤模型中促进颗粒组织形成中的作用.
- 评估hBM-MSCs对关键生长因子,纤维细胞生长因子 (FGF) 和血管内皮生长因子 (VEGF) 在伤口愈合过程中的表达的影响.
主要方法:
- 30只由阿洛克桑诱导的糖尿病大鼠被分为对照组 (PBS) 和治疗组 (hBM-MSCs).
- 造成了全厚的背部烧伤,并在受伤后的3,7和14天收集了皮肤组织.
- 免疫组织化学染色被用于量化FGF和VEGF的表达,并使用Tukey的t-test分析数据.
主要成果:
- 与对照组相比,hBM-MSC治疗组在3,7和14天的FGF水平呈现出统计学上显著的增加 (p=0.017在14日).
- 治疗组的VEGF表达在第3天和第7天增加,但在第14天呈现下降,两组之间没有统计学上显著的差异.
- 这些发现表明hBM-MSCs在糖尿病情况下在烧伤愈合期间调节生长因子表达.
结论:
- hBM-MSCs在糖尿病烧伤中增强了颗粒组织的形成,主要是通过FGF的上调.
- 在新血管化的早期阶段,FGF似乎至关重要,而VEGF的作用在新血管形成的后期阶段更为突出.
- hBM-MSCs代表了一种有前途的治疗剂,可以改善糖尿病患者的烧伤愈合.

Clinical Applications of Epidermal Stem Cells
2.7K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

Tissue Renewal without Stem Cells
1.7K
After cellular or tissue damage, the resident stem cells present in the human body can locally repair and regenerate the damaged tissue or organ. However, even though some tissues do not have stem cells, they can repair and regenerate with the help of pre-existing cells. For example, beta cells of the pancreas and hepatocytes of the liver can divide to renew and regenerate the tissue. Here, both cell division and cell death are well regulated by homeostasis.

Mesenchymal Stem Cells
4.6K
Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their...
