通过局部鼻腔粘膜注射建立CRS的老鼠模型.
在CRS模型大鼠的鼻腔粘膜中注射NM-EMSC或盐水.
在注射后的不同时间点对鼻腔粘膜组织进行组织学分析 (HE,马森三色,PAS染色).

主要成果:

孤立的NM-EMSCs表达了特征标记物 (CD73,CD105,CD90) 并表现出多效.
在CRS模型大鼠中,鼻腔粘膜显著加厚,炎症细胞透,原蛋白和粘素沉积增加.
随着时间的推移,NM-EMSC治疗逐渐缓解了鼻腔粘膜的加厚,减少了炎症细胞的透,并减少了原蛋白和粘素的分布.

Mesenchymal Stem Cells

Mesenchymal Stem Cells

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...

Clinical Applications of Epidermal Stem Cells

Clinical Applications of Epidermal Stem Cells

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...
