Osteogenic differentiation of intact human amniotic membrane

Biomaterials, 2010
Tissue engineering strategies usually require cell isolation and combination with a suitable biomaterial. Human amniotic membrane (AM) represents a natural two-layered sheet comprising cells with proven stem cell characteristics. In our approach, we evaluated the differentiation potential of AM in toto with its sessile stem cells as alternative to ...

Staining Properties of Deepithelialized Human Amniotic Membrane

Cornea, 2005
The surgical use of human amniotic membrane (HAM) can be challenging because of its transparency, thin structure, and adhesive quality. Staining of HAM has been proposed to facilitate intraoperative visualization. We evaluated the in vitro staining properties of deepithelialized HAM using 5 vital dyes.Deepithelialized HAM was stained with indocyanine ...

Drug Reservoir Function of Human Amniotic Membrane

Journal of Ocular Pharmacology and Therapeutics, 2011
The aim of the study was the quantitative pharmacokinetic evaluation of drug release from pretreated amniotic membrane (AM) in vitro.Cryopreserved AM pieces soaked in 3% ofloxacin ophthalmic solution were mounted in vertical Franz-diffusion cell system equipped with autosampler.

Staining Characteristics of Preserved Human Amniotic Membrane

Cornea, 2003
Amniotic membrane is an ultra-thin cellophane-like membrane that is used in ocular surface reconstruction. We evaluated the staining characteristics of commonly available dyes on preserved human amniotic membrane to aid in handling of amniotic membrane during transplantation.Five dyes, indocyanine green (2.5%, 1.0%, and 0.5%), fluorescein (0.25%), rose

Human Amniotic Membrane to treat macular holes that failed to close, Sulfur Hexafluoride endotamponade versus air endotamponade: a prospective comparative study.

Retina, 2020
PURPOSE To determinate the efficacy of the human amniotic membrane plugs with sulfur hexafluoride versus human amniotic membrane plug with air as endotamponade to treat macular holes that failed to close after vitrectomy plus internal limiting membrane ...

Mesenchymal Stem Cells from Human Amniotic Membrane

2014
[Abstract] The human amnion or amniotic membrane (HAM) has emerged as a novel and alternative source of stem cells. This tissue presents a reservoir of two types of stem cells from different embryological origins: human amniotic mesenchymal stem cells (hAMSCs), derived from the mesodermal germ layer, and human amniotic epithelial cells (hAECs), derived

Human amniotic membrane transplantation

2000
Purpose. To evaluate the effectiveness of amniotic membrane transplantation (AMT) in eyes with ocular surface disease. Methods. Amniotic membranes, prepared according to Tissue Bank International Protocol, were from Lions Croatian Eye Bank. Retrospective study was made in 45 eyes that underwent AMT in a period between 1998-1999. Indications for surgery

Biological Activities of a Human Amniotic Membrane Interferon

Placenta, 1999
In order to characterize further the human amniotic membrane interferon (IFN-AM), an interferon antigenically unrelated to human IFN-alpha, -beta, and -gamma or TNF, we analysed its biological activities. Here, we present direct evidence of its ability to affect cell growth and to induce the IFN-stimulated genes (ISGs) 6-16 and 2'-5' oligoadenylate ...
