Abstract
Located in the basal epidermis and hair follicles, melanocytes of the integument are responsible for its coloration through production of melanin pigments. Melanin is produced in a type of lysosome-related-organelle (LRO) called the melanosome. In humans, this skin pigmentation acts as an ultraviolet radiation filter. Abnormalities in the division of melanocytes are quite common, with potentially oncogenic growth usually followed by cell senescence producing benign naevi (moles), or occasionally, melanoma. Therefore, melanocytes are a useful model for studying both cellular senescence and melanoma, as well as many other aspects of biology such as pigmentation, organelle biogenesis and transport, and the diseases affecting these mechanisms. Melanocytes for use in basic research can be obtained from a range of sources, including surplus postoperative skin or from congenic murine skin. Here we describe methods to isolate and culture melanocytes from both human and murine skin (including the preparation of mitotically inactive keratinocytes for use as feeder cells). We also describe a high-throughput transfection protocol for human melanocytes and melanoma cells. © 2023 The Authors. Current Protocols published by Wiley Periodicals LLC.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
