Printing quality is highly influenced by the various treatments and methods used in creating paper and enhancing the paper surface. Consumers are most concerned with the paper-ink interactions which vary for certain types of paper due to different chemical properties of the surface. [8] Inkjet paper is the most commercially used type of paper.
Micro-mass cultures of C3H-10T1/2 cells at varied oxygen tensions stained with Alcian blue. A commonly applied definition of tissue engineering, as stated by Langer [3] and Vacanti, [4] is "an interdisciplinary field that applies the principles of engineering and life sciences toward the development of biological substitutes that restore, maintain, or improve [Biological tissue] function or a ...
Tissues are embedded in a harder medium both as a support and to allow the cutting of thin tissue slices. [9] [5] In general, water must first be removed from tissues (dehydration) and replaced with a medium that either solidifies directly, or with an intermediary fluid (clearing) that is miscible with the embedding media.

Ground substance is active in the development, movement, and proliferation of tissues, as well as their metabolism. Additionally, cells use it for support, water storage, binding, and a medium for intercellular exchange (especially between blood cells and other types of cells). Ground substance provides lubrication for collagen fibers. [2]
Tissue culture is the growth of tissues or cells in an artificial medium separate from the parent organism. This technique is also called micropropagation . This is typically facilitated via use of a liquid, semi-solid, or solid growth medium , such as broth or agar .
The sample of tissue is immersed in fixative solution for a set period of time. The fixative solution must have a volume at least 10 times greater than the volume of the tissue. [6] In order for fixation to be successful, the fixative must diffuse throughout the entire tissue, so tissue size and density, as well as type of fixative must be ...
Microscopic view of a histologic specimen of human lung tissue stained with hematoxylin and eosin. Haematoxylin and eosin staining is frequently used in histology to examine thin tissue sections. [10] Haematoxylin stains cell nuclei blue, while eosin stains cytoplasm, connective tissue and other extracellular substances pink or red. [10]
In biology, tissue is an assembly of similar cells and their extracellular matrix from the same embryonic origin that together carry out a specific function. [1] [2] Tissues occupy a biological organizational level between cells and a complete organ. Accordingly, organs are formed by the functional grouping together of multiple tissues. [3]
