Answer:
Logistic growth
Explanation:
The curve has a period of exponential growth, but then levels off at a stable size. growth whose rate becomes ever more rapid in proportion to the growing total number or size.
When stem cells grown on hard, rigid surface, then they became bone cells. Researchers demonstrate in Nature materials that human mesenchymal stem cells grown on a rigid substrate for some time become biased toward differentiating into bone-cell lineage, whereas cell grown on softer surfaces are just likely to eventually follow a bone or fat cell fate.
