Tissue distribution of stem cell factor in adults

Area of Science:

• Cell Biology
• Immunology
• Developmental Biology

Background:

• Stem cell factor (SCF) is a crucial cytokine for development.
• SCF plays vital roles in gametogenesis, hematopoiesis, mast cell development, stem cell function, and melanogenesis.

Purpose of the Study:

• To measure the concentration and distribution of SCF in adult humans and mice.
• To identify specific tissues with high SCF expression in adulthood.

Main Methods:

• Gene expression analysis
• Tissue staining
• Organ protein lysate analysis

Main Results:

• SCF expression persists in various cell types and tissues into adulthood.
• High SCF expression in adult humans was observed in the stomach, spleen, kidney, lung, and pancreas.
• High SCF expression in adult mice was noted in the esophagus, ovary, uterus, kidney, and small intestine.

Conclusions:

• SCF is continuously expressed in multiple adult tissues.
• Organ-specific SCF concentrations in adults may correlate with SCF/CD117-related disease risks.
