AMNIOTIC MEMBRANE TRANSPLANTATION FOR OCULAR SURFACE RECONSTRUCTION IN VETERINARY MEDICINE
The fetal membrane is composed by the chorion, allantois and amnion. The AM is the inner layer. It consists of a single layer of ectodermally derived cuboidal to columnar cells, which form the epithelium, a basement membrane that connects with the chorion by a layer of mesenchyme which contains …

Determining the beneficial properties of bovine amniotic membrane and its efficacy as a therapy for corneal healing
… healing. In this dissertation work, bovine amniotic membrane homogenate (BAMH) has been investigated to evaluate its efficacy as therapy during corneal healing. The first step was to confirm if BAMH contains tissue inhibitor of metalloproteinases (TIMPs), the most effective metalloproteinase …

Clinical Applications of Stem Cells in Ocular Surface Reconstruction.
… expansion of epithelial and endothelial cells on amniotic membrane for the treatment of ocular disorders. This thesis is primarily a microscope-based study and documents the findings of several investigations designed to refine tissue engineering of the cornea. Light, scanning and transmission …

Characterization of pregnancy-associated glycoproteins and progesterone as a predictor of twins and conceptus loss in high-risk pregnancy Holstein cows
… (SH, <60 beats per minute, n = 11), extra amniotic membrane (EM, additional amniotic membrane, n=3). A cohort of twins (TW, n = 41) diagnosed at day 37 post-AI was also enrolled. Twins were also subgroups in unilateral (UT, n=17) and bilateral (BT, n=24). Each HR and TW cow was paired with …

Lesioni degenerative e meccanismi di riparo della superficie oculare: lo pterigio e le deficienze delle cellule staminali del limbo (LSCD). Studio immunoistochimico e tecniche di coltura cellulare
… of human hemi-corneas (epithelium+stroma) on amniotic membrane, using primary keratocytes and limbal stem cells derived by human cornea. The results demonstrated that the complex represented by a well-differentiated epithelium taken together with a model resembling stroma, has developed on the …

Bioinspired alterations of collagen-glycosaminoglycan scaffolds for tissue regeneration applications
… the anti-inflammatory matrix of the amniotic membrane into the collagen ECM analog, we sought to provide a biomaterial that would temper this inflammatory response to allow for tissue regeneration. This fetal environment-inspired material was studied in fibroblast, stem, and immune …

Primary culture of human limbal-corneal epithelial cells under different conditions
… on cell culture inserts and denuded human amniotic membrane (dHAM) for properties associated with LSCs and to understand the human limbal stem-cell biology in vitro with and without 3T3 feeder cells. In particular, the expression of stem cell markers and colony-forming efficiency in …

HEPATIC DIFFERENTIATION OF HUMAN AMNIOTIC EPITHELIAL CELLS AND IN VIVO THERAPEUTIC EFFECT ON ANIMAL MODEL OF CIRRHOSIS
HUMAN AMNIOTIC EPITHELIAL CELLS (HAECS) HAVE BEEN TOUTED AS AN IDEAL CANDIDATE FOR HEPATOCYTE DERIVATION. AFTER IN VITRO HEPATIC DIFFERENTIATION, HAEC-HEP CELLS SHOWED DIFFERENTIAL REGULATION IN GENES INVOLVED IN LIVER FUNCTION, CYP450 ACTIVITIES AND LIVER TRANSCRIPTION FACTORS. IMMUNOFLUORESCENCE …

Utilização de membrana amniótica canina como bandagem no tratamento de úlcera experimental da córnea estudo clínico, histológico e morfométrico em coelhos
A membrana amniótica tem sido amplamente utilizada na reparação de úlceras de córnea, demonstrando resultados satisfatórios por possuir efeito antiadesivo, propriedades bacteriostáticas, promover a proteção da lesão, reduzir a dor, auxiliar na epitelização e não possuir imunogenicidade. Esta …
