Epidermal melanin is induced by topical application of forskolin in a murine model of the fair-skinned UV-sensitive human. Pharmacologic manipulation of cAMP levels in the skin and epidermal darkening strongly protect against UV-mediated inflammation (sunburn) as measured by the minimum erythematous dose (MED) assay.

Multiplexed immunofluorescence enables sequential labeling of multiple antibody markers within a single tissue section to support spatial analysis of tissue architecture and cell populations. Here, a workflow for multiplex detection of senescence-associated, structural, and immune markers is presented, including manual and automated slide preparation, iterative imaging, and single-cell analysis using digital pathology software.

The ability to produce transgenes for Caenorhabditis elegans using genomic DNA carried by fosmids is particularly attractive as all of the native regulatory elements are retained. Described is a simple and robust procedure for the production of transgenes via recombineering with the galK selectable marker.

We developed two sets of tracing combinations in Rosa26tdtomato (ubiquitously expressed in all cells)/Cre (specifically expressed in chondrocytes) mice: one with 2.3Col1a1-GFP (specific to osteoblasts) and one with immunofluorescence (specific to bone cells). The data demonstrate the direct transformation of chondrocytes into bone cells.
FAQs
A panel of MITF, tyrosinase, DCT, and PMEL can provide complementary evidence rather than relying on one readout. MITF reflects melanogenic regulation, whereas tyrosinase reports an enzyme at the entry point of melanin production. Including additional proteins helps characterize pigment-cell state and melanogenesis more broadly in developmental samples.
Tyrosinase links marker readouts to biochemical activity because it converts tyrosine through a series of enzymatic reactions that initiate melanin production. Detecting tyrosinase can therefore add functional context to indicators of pigment-cell identity or melanogenic regulation. In developmental samples, this distinction helps relate differentiation to the emergence of pigment-producing capacity.
Comparing marker presence or activity across developmental samples can help trace neural crest-derived melanocytes as they differentiate. MITF and other melanogenic proteins provide evidence about pigment-cell development, while pigmentation patterns in embryonic tissues show how these cells are represented within developing structures. This approach connects lineage tracing with tissue patterning.
The choice depends on whether the study emphasizes molecular regulation, pigment-cell identification, or tissue-level pigmentation. Molecular indicators can examine regulators and proteins, cellular indicators can locate pigment-producing cells, and histological indicators can characterize pigmentation within tissues. Combining these levels supports a more complete interpretation of developmental samples, organoids, and model organisms.
Embryonic tissues, organoids, and model organisms provide complementary settings for examining pigment-cell differentiation and pigmentation. Embryonic material can reveal developmental patterns, organoids can support analysis of pigment-cell behavior in a tissue-like model, and model organisms allow pigmentation to be characterized in an established biological context. Marker profiles help compare these systems.
These markers connect normal pigment-cell development with disease-related investigation. In pigmentation-disorder studies, they can help characterize altered melanin synthesis or pigment-cell differentiation. In melanoma research, the same markers support analysis of melanogenic regulation and pigment-cell characteristics. Their broader value comes from linking molecular signals with lineage specification and tissue patterning.
