Xx Cel — Models //free\\

Choosing the right cell model is critical for reproducible, translatable results. This paper provides a decision matrix comparing commonly used models (primary cells, immortalized lines, iPSCs, organoids, microfluidic chips). We include failure case analyses (e.g., why a drug works in Caco-2 cells but fails in human trials) and a protocol for validating model “fidelity” using transcriptomic alignment with primary human tissue. The appendix contains a one-page lab reference card.

Sex chromosome complement (XX vs XY) influences cellular physiology independently of hormonal status. This paper provides a protocol for establishing primary and induced pluripotent stem cell (iPSC)-derived XX cell models, including quality controls (karyotyping, X-inactivation status). We demonstrate their utility in identifying sex-specific drug toxicities and modeling autoimmune disorders (e.g., lupus, more common in XX individuals). Researchers can apply this framework to reduce male bias in preclinical studies. xx cel models
