The most useful of all systems, however, breaks downanimaltissues into four classes based on the functions that the tissues perform. The first class includes all those tissues that serve an animal’s needs forgrowth, repair, and energy; i.e., the assimilation, storage, transport, andexcretion...
Epithelial tissue functions to absorb, secrete, and excrete substances. In the intestines, this tissue absorbs nutrients duringdigestion. Epithelial tissue in glands secretehormones, enzymes, and other substances. Epithelial tissue in the kidneys excrete wastes, and in the sweat glands excreteperspiration...

Using DESeq2 normalized bulk-seq gene expression data across GTEx’s 54 tissues and 17,382 samples, we curated an overview of the matrisome’s transcriptome. Using the median of normalized tissue counts, a Kendall’s τ correlation was generated between the 54 tissue types limited to the core...
1. Describe the 4 types of tissues. Within your discussion, compare and contrast the cells, microscopic characteristics, locations, functions of each tissue type, and discuss homeostasis. 2. Choose one tissue type and discuss a specific type of cancer wh ...
The pulmonary system is composed of a variety of epithelial cell populations residing in distinct anatomical locations. Of these, the alveolar epithelial gas exchange surface consists of two cell types, the type I and type II pneumocytes, also known as alveolar epithelial type I and type II (AEI...
functions in their native setting [2,4]. Thus, natural biomaterials, when repopulated with autologous or genetically engineered cells, can serve as the ideal template for the design of living implants for specific applications in TE and regenerative medicine. Consequently, they are a good choice ...
Tissue wound repair is a complex process in which a variety of cellular functions such as chemotaxis, angiogenesis, cell proliferation, extracellular matrix formation and the “cleansing” macrophage coexist, sequentially and covertly. These functions form a complex in which three relatively distinct ...
proteins, which revealed the prevalent region-to-region heterogeneity in the distributions of proteins across the brain. Such resource will not only expand our knowledge of spatially-resolved brain biology and functions, but also provides the basis to inform research concerning brain disease and ...
However, the multiple cell types within a tissue don't just have different functions. They also have different transcriptional programs and may well divide at different rates. Proper regulation of these rates is essential to tissue maintenance and repair. The spatial organization of the cells that ...
