This study was approved by the ethics committee of the University of Saarland and it was conducted according to the principles for research use of human tissue of the World Medical Association Declaration of Helsinki. Written and informed consent for the use of their tissue for scientific research was obtained for all subjects.
Newborn calf serum
Newborn calf serum is a biological supplement derived from the blood of newborn calves. It provides a complex mixture of proteins, growth factors, and other biomolecules that support cell growth and proliferation in cell culture applications.

3T3-L1 Cell Differentiation Assay
Knee Wear Simulator Protocol
Cell Line Maintenance and Transfection
Plasmid transfection was carried out by polyethylenimine (PEI; Polysciences) method, according to the manufacturer's protocol.
Cells stably expressing the indicated proteins were established by standard retroviral infection, and selected in 2 μg/ml puromycin (Ameresco) or 50 μg/ml hygromycin B (Ameresco) for 7 days.
Imaging Human Corneal Endothelium and Descemet's Membrane
A total of 10 samples was used. Based on storage time, they were divided into three groups: Short-term storage (STS): <1 week of storage (n ¼ 4) Medium-term storage (MTS): between 3 and 4 weeks of storage (n ¼ 3) Long-term storage (LTS): between 8 and 13 weeks of storage (n ¼ 3) Samples had ECDs of 1733 6 54 and 1824 6 53 cells/mm 2 when calculated manually and with the NAVIS cell count system (Nidek Technologies, Erlangen, Germany), respectively. ECDs were determined in the central region of the cornea.
For image acquisition, the samples were washed in PBS and placed in glass-bottom petri dishes. Live-cell imaging solution (#A14291DJ; Life Technologies, Carlsbad, CA, USA) was used to ensure the cornea hydration during imaging. For imaging the endothelium and the Descemet's membrane, the samples were flipped.
All experiments were conducted following the tenets of the World Medical Association Declaration of Helsinki for research using human samples.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
