WebBroadly, the macroscopic growth models described below can be binned into three categories: (i) exponential, (ii) sigmoidal, and (iii) power law models. Exponential models are characterized by a long period of constant proliferation cell cycle time, while sigmoidal models have eventual slowed growth until an eventual plateau. WebJul 1, 2024 · It was also noted that sigmoidal growth kinetics were observed as a result of secondary nucleation even in the absence of rate-limiting primary nucleation events. This is in contrast to the classical homogeneous-nucleation depended polymerization where the initial aggregation determines the lag phase of fibrillation kinetics.
