Evaluation of interface quality in organ-cultured lamellar corneal transplants [PDF]

open access: yes, 2012
Background: With increasing numbers of lamellar keratoplasties, eye banks are challenged to deliver precut lamellar donor tissue. In Europe, the most common technique of corneal storage is organ culture which requires a deswelling process before surgical

CULTURES OF ORGANIZED TISSUES [PDF]

open access: yesJournal of Experimental Medicine, 1922
An artificial organism, if one may so term it, composed of a complex of tissues, was cultivated for a long period of time. Small fragments of intestine from chick embryos 20 to 21 days old were placed in a suitable medium. The epithelium proliferated and completely covered the fragment of intestine after 4 to 6 days. A small body was thus formed, round

SARS-CoV-2 Omicron Induces Enhanced Mucosal Interferon Response Compared to other Variants of Concern, Associated with Restricted Replication in Human Lung Tissues

open access: yesViruses, 2022
SARS-CoV-2 Omicron variant has been characterized by decreased clinical severity, raising the question of whether early variant-specific interactions within the mucosal surfaces of the respiratory tract could mediate its attenuated pathogenicity.

Genotoxicity of nitroso compounds and sodium dichromate in a model combining organ cultures of human nasal epithelia and the comet assay [PDF]

open access: yes, 2001
Genotoxic effects of xenobiotics are a possible step in tumor initiation in the mucosa of the upper aerodigestive tract. Using the comet assay, detecting genotoxicity in human tissue has been restricted to single incubations in vitro, but in vivo most ...

A novel and cost-effective ex vivo orthotopic model for the study of human breast cancer in mouse mammary gland organ culture

open access: yesBiology Open, 2020
Mouse mammary organ culture (MMOC) is used to evaluate the efficacy of chemopreventive agents against the development of carcinogen-induced preneoplastic lesions and is highly correlative to in vivo carcinogenesis models. Here, we developed a new ex vivo

A respirometer for organ cultures [PDF]

open access: yesBiochemical Journal, 1965
1. A differential respirometer that can measure the oxygen uptake of organ cultures for periods of several days is described. 2. Diethanolamine is used as an external carbon dioxide buffer so that oxygen consumption can be measured in the presence of physiological concentrations of carbon dioxide and bicarbonate. 3.
