Cell isolation is the process of separating individual living cells from a solid block of tissue or cell suspension. While some types of cell naturally exist in a separated form (for example blood cells ), other cell types that are found in solid tissue require specific techniques to separate them into individual cells.
Primary cell culture is the ex vivo culture of cells freshly obtained from a multicellular organism, as opposed to the culture of immortalized cell lines.In general, primary cell cultures are considered more representative of in vivo tissues than cell lines, and this is recognized legally in some countries such as the UK (Human Tissue Act 2004).

Laser-capture microdissection (LCM) is a method to procure subpopulations of tissue cells under direct microscopic visualization. LCM technology can harvest the cells of interest directly or can isolate specific cells by cutting away unwanted cells to give histologically pure enriched cell populations.
Cell isolation: Process of separating individual living cells from a solid block of tissue or cell suspension: Cell biology: Centrifugation: Use of centrifugal force to separate particles from a solution according to their size, shape, density, medium viscosity, and rotor speed: Cell biology, Biochemistry: CRISPR gene editing
Another laboratory separation tool is the affinity magnetic separation (AMS), which is more suitable for the isolation of prokaryotic cells. [2] IMS deals with the isolation of cells, proteins, and nucleic acids through the specific capture of biomolecules through the attachment of small-magnetized particles, beads, containing antibodies and ...
These primary cells can then be further expanded and transferred into fresh dishes through micropropagation. Explant culture can also refer to the culturing of the tissue pieces themselves, where cells are left in their surrounding extracellular matrix to more accurately mimic the in vivo environment e.g. cartilage explant culture, [ 3 ] or ...

Traditional purification method used to yield a reasonable purity level of mouse hematopoietic stem cells, in general, requires a large (~10–12) battery of markers, most of which were surrogate markers with little functional significance, and thus partial overlap with the stem cell populations and sometimes other closely related cells that ...
