[2025-09-30T20:23:45.568142] [PI reasoning] **Reviewing osteogenesis findings**

I’m looking at search results about distraction osteogenesis. The first article describes a "permanent growth zone" with fibroblast-like cells and osteoblastic elements, but it doesn’t mention osteoclasts. The phrase "zone of stimulation" doesn't appear, though it seems to be an older concept. I’ll make sure to reference the relevant study, Mikhaĭlova & Shtin 1978, which doesn’t mention osteoclasts. I can craft my answer emphasizing that proliferating fibroblasts lead to bone formation in this zone without osteoclasts.
