Protocol for induction of human kidney cell fibrosis.

Here, we present a protocol for inducing fibrosis in human kidney-2 (HK2) cells followed by quantitative real-time PCR analysis of fibrosis-related genes. We describe steps for growing and expanding cells, inducing HK2 fibrosis, and collecting cells for downstream applications. Given the limited cell quantity in culture flasks and the challenges of cell collection, we utilized 10-cm Petri dishes for cell harvesting, with each experimental group comprising five replicate samples. For complete details on the use and execution of this protocol, please refer to Zhang et al..
