まとめ
この研究は、高度な単一細胞および空間トランスクリプトミクスを使用してコロンがんの生態系をマッピングします。マウスと人間の間で保存された細胞近傍を明らかにし、空間的配置を疾患の進行と患者の予後に結び付けます。
科学分野:
- 単一細胞ゲノミクス
- 空間トランスクリプトミクス
- がん生物学
背景:
- 腫瘍生態系の特徴を理解するには、細胞組成と空間的配置の理解が必要です。
- 腫瘍内の空間的関係と機能的相互作用を定義することは依然として困難です。
主な方法:
- 単一細胞RNAシーケンス（scRNA-seq）、Slide-seq空間トランスクリプトミクス、およびin situマルチプレックスRNA解析を組み合わせました。
- 誘導性遺伝子CRCマウスモデルをプロファイリングしました。

01:33Adult Stem Cells
Stem cells are undifferentiated cells that divide and produce more stem cells or progenitor cells that differentiate into mature, specialized cell types. All the cells in the body are generated from stem cells in the early embryo, but small populations of stem cells are also present in many adult tissues including the bone marrow, brain, skin, and gut. These adult stem cells typically produce the various cell types found in that tissue—to replace cells that are damaged or to continuously renew...
02:30Metastasis
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

01:13Cell Diversity
The concept of a cell started with microscopic observations of dead cork tissue by Robert Hooke in 1665. Hooke coined the term "cell" based on the resemblance of the small subdivisions in the cork to the rooms that monks inhabited, called cells. About ten years later, Antonie van Leeuwenhoek became the first person to observe the living and moving cells under a microscope. In the century that followed, the theory that cells represented the basic unit of life developed.

00:55Microvilli
Microvilli are tiny finger-like projections found on the surface of certain cells. Their purpose is to increase the surface area of the cell's apical surface, resulting in more effective absorption or secretion of substances.
These microvilli are predominantly present in cells lining the small intestine, kidney tubules, and certain cells in the respiratory and reproductive systems. By significantly expanding the surface area of the cell membrane, microvilli enhance the cell's capacity to...
