RESULTS: After 10-days culture with cytokines and CPLA, PBMC developed into mature DCs with typical morphological characteristics and high expressions of CD1a, CD83, CD80 and CD86 on the cellular surface (P<0.05).
Objective:To study the distribution and morphological characteristics of GD1a+dendritic cells (DC) and the expression of vascular endothelial growth factor (VEGF) in laryngeal carcinoma,and to investigate the relationship between the expression of VEGF and CD1a~+ DC density in laryngeal carcinoma.
By comparing the morphological characteristics of these four species,we found that the patterns of adaptation to the arid environment were different from each other in the four desert Caragana species.
The study showed that the mechanism of the planting survival on the dry sandy land in the draught was the physiology and morphological characteristics of forest trees forming the enormous and developed root system network so as to be suitable for the dry habitat and to guarantee the planting survival.
The morphological characteristics of the newly released super hybrid rice in South China, Yueza122, Fengyou428, Peiza67, and super conventional varieties, Guangchao 3, Shengtai 1 at the active tillering stage in both early and latecrops were investigated.
The results showed that there was difference on root morphological characteristics in two genetic types, especially after R5 stage, the root bi-omass, root volume and root length of high yielding line Hai-560 were higher than that of Guan-009;
The sap flow measurement was used in combination with morphological characteristics of tree and forest structure to calculate the whole-tree transpiration (E), stand transpiration (Et), and mean canopy stomatal conductance (gc).
There was no distinctive difference in proportions of morphological characteristics among them.
Species with similar morphological characteristics and from the same areas or neighboring geographical regions were clustered together and had close relationships.
Taking the physiological and biochemical traits, the morphological characteristics and 16S rDNA sequence into consideration, the isolate Rennanqilyf33 is a new species.
Four variants of the fungus differed in morphological characteristics and glucose oxidase synthesis.
