Telocytes/CD34+ Stromal Cells in Pathologically Affected White Adipose Tissue

Area of Science:

• Adipose tissue biology
• Cellular pathology
• Stromal cell research

Background:

• Telocytes/CD34+ stromal cells (TCs/CD34+SCs) play roles in tissue homeostasis.
• Their behavior in pathological adipose tissue remains underexplored.

Purpose of the Study:

• To investigate the presence and role of TCs/CD34+SCs in diverse pathological adipose tissue conditions.
• To explore potential changes in CD34 expression and their function in tumor microenvironments.

Main Methods:

• Review of pathological processes involving adipose tissue.
• Examination of TCs/CD34+SCs in inflammation, amyloidosis, neurogenic processes, and various tumors.
• Analysis of cell conservation, increase, loss, or altered arrangement.

Main Results:

• TCs/CD34+SCs were observed in various pathological states, including inflammation, amyloidosis, and tumors.
• Evidence suggests CD34 expression loss in TCs/CD34+SCs is due to marker changes, not cell disappearance.
• In some metastatic tumors, TCs/CD34+SCs appear to surround neoplastic cells, potentially acting as nurse or isolating cells.

Conclusions:

• TCs/CD34+SCs exhibit dynamic changes in pathological adipose tissue.
• Further research is needed on TCs/CD34+SCs in lipomatosis and obesity.
• The role of TCs/CD34+SCs in tumor progression warrants deeper investigation.
