Uncover the Hidden Complexity of Colon Cancer with Big Data

Colorectal cancer poses a significant health burden. While surgery is effective initially, some patients develop recurrent secondary disease with poor prognosis, necessitating advanced therapies like…
Pancreatic Ductal Adenocarcinoma with 11 Aerobic Glycolysis/Warburg Effect biomarkers shown – BCAT, Glut1, HK2, HTR2B, LDHA, NaKATPase, PCAD, PCK26, PKM2, SMA1, and Vimentin.

Dive into Pancreatic Cancer Research with Big Data

Pancreatic cancer, with a mortality rate near 40%, is challenging to treat due to its proximity to major organs. This story explores the complex biology of pancreatic ductal adenocarcinoma (PDAC),…

Overcoming Challenges with Microscopy when Imaging Moving Zebrafish Larvae

Zebrafish is a valuable model organism with many beneficial traits. However, imaging a full organism poses challenges as it is not stationary. Here, this case study shows how zebrafish larvae can be…
Block-face created by automatic trimming under fluorescence. Mammalian cells of interest, stained with CellTrackerTM Green are visualized within the block-face using the UC Enuity equipped with the stereo microscope M205 FA. In the background a carbon finder grid in black is visible. All samples in the article are created by Felix Gaedke, PhD, CECAD, Cologne, Germany.

如何在块面中自动获取感兴趣的荧光细胞

本文介绍了使用超薄切片超薄切片机自动修整修块功能，获取树脂块面中带有荧光信号的细胞结构。我们展示了如何使用配置有体视显微镜 M205 FA 的超薄切片超薄切片机 UC Enuity ，来识别感兴趣的荧光细胞，如何自动修整包含细胞的块面，以及如何在切片中观察细胞而无需转移到外部显微镜。
