Intestinal absorption is a key toxicokinetics parameter. While the colon carcinoma cell line Caco-2 is the most used in vitro model to estimate human drug absorption, models representing other intestinal segments are developed. We characterized the morphology, tissue-specific markers and functionality of three human intestinal cell types: Caco-2, primary human enteroid-derived cells from jejunum (J2), and duodenum (D109) when cultured in the OrganoPlate® 3-lane 40 microphysiological system (MPS) or static 24-well Transwells™.

In vitro models that can faithfully replicate critical aspects of kidney tubule function such as directional drug transport are in high demand in pharmacology and toxicology. Accordingly, development and validation of new models is underway. The objective of this study was to characterize physiologic and transport functions of various sources of human renal proximal tubule epithelial cells (RPTECs).

Various attempts have been made to elucidate the mechanisms of human lung development, its physiological functions, and diseases, in the hope of new drug discovery. Recent technological advancements in experimental animals, cell culture, gene editing, and analytical methods have provided new insights and therapeutic strategies. However, the results obtained from animal experiments are often inconsistent with those obtained from human data because of reproducibility issues caused by structural and physiological differences between mice and humans.

Aims: The purpose of this study was to investigate the prognostic significance of cholesterol uptake genes in predicting the survival of breast cancer patients.
Background: Cholesterol plays a crucial role in the homeostasis of tumor cells. It is known that cholesterol levels can influence important parameters of the disease, such as sensitivity to therapy, progression, and metastasis of cancer.

The regular workshops held by the Center for Alternatives to Animal Testing (CAAT) on biology-inspired microphysiological systems (MPS) taking place every four years, have become a reliable measure to assess fundamental scientific, industrial and regulatory trends for translational science in the MPS-field from a bird's eye view. The 2023 workshop participants at that time concluded that the technology as used within academia has matured significantly, underlined by the broad use of MPS and the steadily increasing number of high quality research publications - yet, broad industry adoption of MPS has been slow, despite strong interest. Academic research using MPS primarily aims to accurately recapitulate human biology in MPS-based organ models in areas where traditional models have been lacking key elements of human physiology, thereby enabling breakthrough discoveries for life sciences.
