Ten years ago, the team at Advanced Cell Technology announced that it had successfully converted human embryonic stem cells into retinal pigment epithelial cells.

Wei Long Ng explained: «The two - step bioprinting strategy involves the fabrication of hierarchical porous collagen - based structures (that closely resembles the skin's dermal region), and deposition of epidermal cells such as keratinocytes and melanocytes at pre-defined positions on top of the biomimetic dermal skin constructs, to create 3D in - vitro pigmented human skin constructs.

Researchers at the RIKEN Center for Developmental Biology in Kobe plan to generate replacement retinal pigment epithelial cells from iPS cells generated from patients suffering age - related macular degeneration.

Researchers at the University of Bonn and the Ludwig - Maximilians - Universität of Munich have decoded a new mechanism of how the immune system can specifically attack pigmented cells of the skin.

Our first results demonstrate our ability to produce retinal precursors (even at a low yield) and mainly Retinal Pigment Epithelial (RPE) cells at a high yield (99 %) from hES and iPS cells.

More specifically, they are looking at the cells that produce the pigment that gives the iris its color.

It aims at evaluating the tolerance to a hESC - derived retinal pigmented epithelium cell transplantation.

Having successfully reconstructed an epidermis using pluripotent stem cells in 2009, Christine Baldeschi's team at I - Stem, has just given it colour: using the same strategy, the researchers have obtained, in vitro, functional melanocytes, the cells that give skin its pigment and protect it from UV rays.

A population of these cells forms a layer deep to the photoreceptors, where they contain intracellular pigment granules and appear superficially like an extra RPE layer, even though they do not express at least two characteristic RPE proteins.

«These white markings occur not because the dogs can not produce pigment but because they completely lack pigment cells in the skin in the areas that have white markings», says Izabella Baranowska Körberg who obtained her PhD degree at SLU on a thesis in which this study was included.

A. Melanoma is a cancer of pigment cells and all melanomas share some characteristics but they also differ: the genetic changes which define cancers occur in the cancer cells at random and cancers are all therefore a little different.

They went on to show that Sox10, a factor needed for the formation of skin pigment cells from neural crest stem cells during development, was present at high levels in naevi and melanoma samples obtained from both the mouse model and human patients.

(D) Large pigmented cells are observed in the subretinal space at 13 week post-graft.

The large pigmented CD68 - positive cells observed in the subretinal space at 13 weeks are likely to be macrophages / microglia filled with melanin [46], [47] from the transplanted human iPS - RPE cells.

The retinal pigment epithelium (RPE) is a monolayer of cells, residing at the back of the eye between Bruch's membrane and the retina, which is essential for photoreceptor function and survival.

At 13 weeks, two distinct CD68 - positive cell populations were observed, one type was small and non-pigmented (Fig. 8C) and the other consisted of large highly pigmented cells (Fig. 8 D).

This is especially true for white or lightly pigmented cats that are at an increased risk for getting squamous cell cancer on their ears, nose and eyelids.

When you look at the algae cells, the dry pigments that we use for our ink, you can literally touch the carbon material that previously was carbon dioxide.
