Snail directly controls FSC proliferation. Compromised Snail expression decreases FSC proliferation; while overexpressing of Snail promotes FSC division.

Endogenous Snail does not negatively control E-cadherin expression, while excessive Snail moderately suppresses E-cadherin expression.

Endogenous Snail is not required for FSC maintenance, whereas exogenous Snail prolongs FSC lifespan and increased competition for niche occupancy.
