A new murine esophageal organoid culture method and organoid-based model of esophageal squamous cell neoplasia

iScience, 2021
Summary: Organoids mimic the physiologic and pathologic events of organs. However, no consensus on esophageal organoid (EO) culture methods has been reached.

Integrating extrusion complex-associated pattern to predict cell type-specific long-range chromatin loops

iScience, 2022
Summary: The chromatin loop plays a critical role in the study of gene expression and disease. Supervised learning-based algorithms to predict the chromatin loops require large priori information to satisfy the model construction, while the prediction ...

A human multi-cellular model shows how platelets drive production of diseased extracellular matrix and tissue invasion

iScience, 2021
Summary: Guided by a multi-level “deconstruction” of omental metastases, we developed a tetra (four cell)-culture model of primary human mesothelial cells, fibroblasts, adipocytes, and high-grade serous ovarian cancer (HGSOC) cell lines.

A quantitative micro-tomographic gut atlas of the lepidopteran model insect Manduca sexta

iScience, 2023
Summary: The tobacco hornworm is used extensively as a model system for ecotoxicology, immunology and gut physiology. Here, we established a micro-computed tomography approach based on the oral application of the clinical contrast agent iodixanol ...

Spatio-temporal optical coherence tomography provides full thickness imaging of the chorioretinal complex

iScience, 2022
Summary: Despite the rapid development of optical imaging methods, high-resolution in vivo imaging with penetration into deeper tissue layers is still a major challenge. Optical coherence tomography (OCT) has been used successfully for non-invasive human

The protein corona from nanomedicine to environmental science

Nature Reviews Materials, 2023
The protein corona spontaneously develops and evolves on the surface of nanoscale materials when they are exposed to biological environments, altering their physiochemical properties and affecting their subsequent interactions with biosystems.

GATA1 deletion in human pluripotent stem cells increases differentiation yield and maturity of neutrophils

iScience, 2023
Summary: Human pluripotent stem cell (hPSC)-derived tissues can be used to model diseases in cell types that are challenging to harvest and study at-scale, such as neutrophils.

Response Surface Methodology and Its Applications In Agricultural and Food Sciences

, 2017
From the historical point of view, the article by Box and Wilson [1] is considered to be the first for having laid the foundations for RSM. Some of the early papers that also contributed to the development of RSM include those by Box and Hunter [2] and ...
