The introduction of DNA into the nucleus of an oocyte, embryo, or other cell by injection through a very fine needle.
The direct injection of a sperm into the substance of the egg to produce a fertilisation. This technique is used when there are very few sperm in the ejaculate, when the sperm show poor motility or abnormal structure or have been obtained from the testis or have previously failed to fertilise in conventional IVF treatments. This technique is also called ICSI, which stands for Intracytoplasmic Sperm Injection where the term "cytoplasm" refers to the substance of the egg.
Français] genetic engineering technique that uses a fine-tipped glass needle to inject DNA into a cell.
a technique by which part of one cell is injected into another cell, as DNA into ova or other cells to create transgenic animals.
The injection of a single cell using a micropipet.
A technique used for the insertion of genes from one cell into another cell.
A technique for introducing a solution of DNA into a cell using a fine microcapillary pipet.
he most precise techniques for delivering macro-molecules into specific intracellular compartments of living cells
Injection of tiny amounts of a substance into a microscopic body, such as a single cell.
Microinjection refers to the process of using a micro needle to insert substances at a microscopic or borderline macroscopic level into a single living cell. It is a simple mechanical process in which an extremely fine micro needle penetrates the cell membrane and sometimes the nuclear envelope and releases its contents. Microinjection is normally performed under a specialized optical microscope setup called a micromanipulator.
