We have organized and published these 37 papers to present the research origins associated with tiptop and the fields we continue to follow. The bibliography covers lungs and airways, kidneys, the female reproductive tract and endometrium, cell signaling and systems biology, and liver regeneration. Formal titles, publication years, journals and DOIs are retained.

Why retain both research-source and background papers

Thirty papers in the index list Wei Zuo as a coauthor; we classify these as research-source literature. Six are field-background papers, and one Chinese-language review is included as a reference review. This organization shows the research lineage while retaining the academic context needed to understand the questions involved.

Authors and study content follow the original journal records. Cell, tissue, animal and human studies each have their own research subjects.

Five lines of research organize the collection

The 16 papers on lungs and airways connect airway-cell identity, culture, repair and related methods, while retaining respiratory-research and public-health context. Six kidney papers address cell identification, post-injury states, organoids and repair.

Eight papers on the female reproductive tract and endometrium separately retain epithelial-cell research and background literature on endometrial and menstrual-blood-derived cells. Different cell sources and types are presented according to the subjects of the original studies.

Six papers on cell signaling and systems biology cover basic questions involving receptors, signaling regulation, protein interactions and body size. One further paper on liver regeneration records another area of tissue and cell research.

These research sources provide context for our material and translation work. The topical performance of particular products, including CELLshot products, is presented separately through their own finished-product evaluations.
