Melanocytes in regenerative medicine applications and disease modeling.

Melanocytes are dendritic cells localized in skin, eyes, hair follicles, ears, heart and central nervous system. They are characterized by the presence of melanosomes enriched in melanin which are responsible for skin, eye and hair pigmentation. They also have different functions in photoprotection, immunity and sound perception.

Extracellular Vesicles from Ocular Melanoma Have Pro-Fibrotic and Pro-Angiogenic Properties on the Tumor Microenvironment.

Uveal melanoma (UM) is the most common primary intraocular tumor and often spreads to the liver. Intercellular communication though extracellular vesicles (EVs) plays an important role in several oncogenic processes, including metastasis, therapeutic resistance, and immune escape. This study examines how EVs released by UM cells modify stellate and endothelial cells in the tumor microenvironment.

Experimental eye research / short communication format characterization of DNA hydroxymethylation in the ocular choroid.

DNA methylation and hydroxymethylation represent important epigenetic modifications involved in cell differentiation. DNA hydroxymethylation can be used to classify independent biological samples by tissue type. Relatively little is known regarding the genomic abundance and function of 5-hydroxymethylcytosine (5-hmC) in ocular tissues.
