Tissue engineering is the process of putting together scaffolds, cells, and biologically active molecules to make functional tissues. [ 48 ] [ 49 ] It is possible to make meter-long core-shell hydrogel microfibers that contain ECM proteins and mature cells or somatic stem cells in a microfluidic device. and these microfibers have the ...
Natural fibers or natural fibres (see spelling differences) are fibers that are produced by geological processes, or from the bodies of plants or animals. [1] They can be used as a component of composite materials, where the orientation of fibers impacts the properties. [2] Natural fibers can also be matted into sheets to make paper or felt. [3 ...
Elastic fibers stain well with aldehyde fuchsin, orcein, [16] and Weigert's elastic stain in histological sections.. The permanganate-bisulfite-toluidine blue reaction is a highly selective and sensitive method for demonstrating elastic fibers under polarizing optics.
Collagen based implants are used for cultured skin cells or drug carriers that are used for burn wounds and replacing skin. [8] Collagen as haemostat: When collagen interacts with platelets it causes a rapid coagulation of blood. This rapid coagulation produces a temporary framework so the fibrous stroma can be regenerated by host cells.
Cellulose is a polymer made of repeating glucose molecules attached end to end. [4] A cellulose molecule may be from several hundred to over 10,000 glucose units long. Cellulose is similar in form to complex carbohydrates like starch and glycogen. These polysaccharides are also made from multiple subunits of glucose.
The formed elements are the two types of blood cell or corpuscle – the red blood cells, (erythrocytes) and white blood cells (leukocytes), and the cell fragments called platelets [12] that are involved in clotting. By volume, the red blood cells constitute about 45% of whole blood, the plasma about 54.3%, and white cells about 0.7%.
In a mouse model of breast cancer, it was found that metastatic cancer cells were more effective at inducing NET formation compared to less aggressive cells. [27] Additionally, higher levels of NETs were detected in metastatic lesions of breast cancer patients, particularly in those with triple-negative breast cancer , which is known for its ...
Nanofibers were first produced via electrospinning more than four centuries ago. [28] [29] Beginning with the development of the electrospinning method, English physicist William Gilbert (1544-1603) first documented the electrostatic attraction between liquids by preparing an experiment in which he observed a spherical water drop on a dry surface warp into a cone shape when it was held below ...
