The tissue immediately surrounding at least part of the vascular bundles in the leaves of gymno-sperms, e.g. Pinus. Transfusion tissue is composed of tracheids (transfusion tracheids) with conspicuous *bordered pits , and parenchyma cells (transfusion parenchyma) containing tannin-like substances and sometimes starch. The main function of the transfusion tissue is believed to be the transport of materials between the vascular bundles and the mesophyll.
Transfusion tissue in cycas refers to specialized cells within the stems that enable movement of nutrients, particularly in sap. These cells are involved in facilitating the transfer of materials such as sugars and other organic compounds between different parts of the plant, aiding in overall nutrient distribution within the cycas plant.
Transfusion tissue in gymnosperms facilitates the movement of sugars and nutrients between the inner and outer regions of the wood. It helps in distributing resources like water, minerals, and organic compounds throughout the plant.
Cycas rumphii was created in 1839.
Cycas taitungensis was created in 1994.
Cycas, the more accurate name depends on the exact species
Transfusion reaction may also cause a hypersensitivity of the immune system that, in turn, may cause tissue damage within the patient's body.
The scientific name for sago palms is Cycas revoluta.
Scientific name: Cycas inermis,English name: Thornless fern palm.
* in cycas the stems are unbranched while in pinus the stems are branched. * in pinus male or female cones or strobili may be borne on the same tree while in cycas they are on different trees.

If possible, this test should be postponed if the patient has recently undergone a transfusion, because any WBCs from the transfusion may interfere with the tissue typing of the patient's lymphocytes.
