Reprogramming of iPSCs to NPCEC-like cells by biomimetic scaffolds for zonular fiber reconstruction.

ABSTRACT: Ectopia lentis (EL), characterised by impaired zonular fibers originating from non-pigmented ciliary epithelial cells (NPCEC), presents formidable surgical complexities and potential risks of visual impairment. Cataract surgery is the only treatment method for EL, but it leads to the loss of accommodative power of the lens post-operatively. Furthermore, the challenge of repairing zonular ligaments in situ remains a significant global issue. Ocular tissue and aqueous humour samples from patients with EL were subjected to RNA sequencing and Olink high-throughput proteomic analysis, revealing the downregulation of pathogenic genes (FBN1, MFAP2) and upregulation of secretory proteins (IL-12, MMP-1). The high expression of FBN1 and MFAP2 in NPCECs suggests the
