The IOD values of MMP-2 zemogen of corneal neovascularization models were higher than those of normal corneas(6.93±0.75 and 4.99±0.53,t=7.728,P<0.01),and the IOD values of active MMP-2 of corneal neovascularization models were 0.47±0.13,while it showed negative in normal cornea.
The experimental results show that the integration of microsensors for microsurgery robot's end-effector can satisfy the design requirements, and the robotic end trephine can accurately fulfill the surgical task of corneal cutting.
Fast deposition of hydroxyapatite coating on titanium to modify cell affinity of corneal fibroblast in vitro
It is shown for the first time that HA coating can significantly enhance the adhesion and proliferation of rabbit corneal fibroblast in comparison with that of pure Ti.
We studied 56 biopsy samples of conjunctiva and 50 corneal discs excised from 28 patients with acquired keratoconus cornea.
Necrobiotic changes have been revealed in epithelium of the corneal discs going by the pathways of apoptosis-programmed cell death-and oncosis-initial edematic stage of necrobiosis.
Rhesus putative epidermal stem cells are being investigated for their potential use in regenerative corneal epithelium-like cells, which may provide a practical source of autologous seed cells for the construction of bioengineered corneas.
To develop a rabbit corneal endothelial (RCE) cell line, in vitro culture of RCE cells was initiated from Oryctolagus curiculus corneas and a novel RCE cell line was established in this study.
To initiate the primary culture of RCE cells, corneas from rabbit eyes were sliced and attached into glutin-coated wells with endothelial cell surface down.
Corneal antigens were prepared from donor corneas not suitable for surgery.
Samples of a PHEMA sponge were implanted in rabbit corneas and explanted at predetermined time points (2, 4, and 12 weeks).
