Illustation of the stem cell regulation models. A) A schematic drawing of the unperturbed stem cell regulation model. B-C) Schematic drawings of the two different clv1-1 mutant models. B) In the loss-of-signal model the strength of the signal from the active CLV1-receptor is affected. C) In the interference model the two receptors form a complex without function.
