Importantly, akin to HESC - RPE in vivo, cells at the outside edge of the iPS - RPE cell bolus could phagocytose photoreceptor outer segments from the RCS rat, as indicated by the presence of rhodopsin - positive photoreceptor material within the cellular membrane of iPS - RPE labelled with HSM (Fig. 5E).

Photoreceptor outer segments (POS) were isolated from freshly slaughtered porcine eyes using a continuous sucrose gradient as previously described [8], [32].

Interphotoreceptor retinoid - binding protein is the physiologically relevant carrier that removes retinol from rod photoreceptor outer segments.

Lack of protein - tyrosine sulfation disrupts photoreceptor outer segment morphogenesis, retinal function and retinal anatomy.

Rim formation is not a prerequisite for distribution of cone photoreceptor outer segment proteins.

(B - i) Electron microscopy image of a porcine photoreceptor outer segment (POS) adjacent to an iPS - RPE cell following 3 hours co-culture with a porcine retina explant.

The progression of retinal dystrophy in the RCS rat is such that by 13 weeks post-graft most of the ONL has disappeared [33] and the photoreceptor outer segment layer is reduced to a debris zone [40], a finding we observed in dystrophic controls.

Not exact matches

Conservation of visual acuity in the iPS - RPE transplanted eyes was associated with the preservation of photoreceptors in the host outer nuclear layer (ONL — Fig. 7A), identified by the expression of rhodopsin in the outer segments of photoreceptors (Fig. 7A inset, Dystrophic + transplant).

The gene product's precise role is not currently understood but it is thought to anchor regulatory complexes at the photoreceptor connecting cilium, which acts as a bridge between the inner and outer segments of photoreceptor cells [43] as well as having functions in disk morphogenesis [42] and in the structure of the ciliary axoneme [44].
