Areas of the tissues were obtained as follows: the adaxial surface of the epidermis, the abaxial surface of the epidermis, the chlorophyll parenchyma, the sum of the phloem areas, the average phloem area in one vascular bundle, the sum of the areas of the vascular bundle sheaths, the sum of the areas of the vascular bundles, the sum of the areas of the xylem, the average xylem area in one vascular bundle, the sum of the area of fibers, the average fiber area in one vascular bundle, and the whole leaf area captured in the image using square micrometers as the measurement unit.
Among Prellis' Vascular Tissue Blanks are the pre- vascularized 3D Tissue Chip, Organoids, and the Vascular Bundle. The beta test product Do-It-Yourself Organ on a Chip is designed for experienced microfluidics labs to set up their own cell-cell interfaces for toxicology screening with flow across a 20-micrometer interface.

The conductive tissue is surrounded by the fiber tissue to form the vascular bundle (Grosser and Liese 1971).
The anterior vascular bundle offers a higher resistance to the free air.
They quantitatively assessed: (1) diameter of the root; (2) thickness of the root epidermis; (3) count of cores of protoxylem; (4) diameter of the vascular cylinder of the root; (5) proportion of the stomata and (6) subsidiaries cells; (7) size of the bulliform cells; (8) thickness of the foliar mesophyll; (9) thickness of the group of fibers of the abaxial and adaxial foliar rib; (10) diameter of the central vascular bundle of the foliar blade.
Of all cultivars, maximum increase in vascular bundle thickness was observed in Cooperi alba as compared with the other cultivars from polluted area.
