WebFeb 2, 2024 · Early contact inhibition is due to unusually long versions of hyaluronic acid (HA), which is the main non-protein component in the extracellular matrix. Early contact inhibition may be replicated in humans by lengthening HA (Seluanov et al. 2024). Interestingly, Seluanov and Gorbunova found “a very promising molecule that increases … WebFurthermore, uncontrolled growth because of the loss of contact inhibition of proliferation is a hallmark of solid tumors (3, 4). Despite these insights, the underlying regulatory mechanisms of the contact inhibition of proliferation remain poorly understood, although cadherin-mediated cell–cell adhesion is thought to play an important role (2).
