Squamous Epithelial Cells
Urine Squamous Epithelial Cells are flat, thin cells that line the urinary tract and can be detected in the urine. The presence of squamous epithelial cells in the urine is a normal finding, but high levels may indicate contamination of the urine sample or certain genitourinary conditions.
iollo markers that associate with Squamous Epithelial Cells
Arachidonic acid
Arachidonic acid is involved in epithelial cell growth and differentiation. Altered levels may reflect changes in epithelial cell turnover.References

Palmitic acid
Palmitic acid is a key component of epithelial cell membranes. Levels may change with epithelial cell shedding and regeneration.References
