13. In vitro callus induction and micropropagation of Thymus persicus (Lamiaceae), an endangered medicinal plant
Abstract This is the first attempt towards an efficient regeneration protocol for an endangered and valuable medicinal plant, Thymus persicus using in vitro callus induction and indirect organogenesis. Callus induction was performed on MS medium supplemented with different concentrations of NAA and 2,4-D, alone or in combination with BAP and KN. Maximum cal

14. Rat visceral yolk sac cells: viability and expression of cell markers during maternal diabetes
The function of the visceral yolk sac (VYS) is critical for embryo organogenesis until final fetal development in rats, and can be affected by conditions such as diabetes. In view of the importance of diabetes during pregnancy for maternal and neonatal health, the objective of this study was to assess fetal weight, VYS cell markers, and viability in female W

15. Development of the endocrine pancreas and novel strategies for β-cell mass restoration and diabetes therapy
Diabetes mellitus represents a serious public health problem owing to its global prevalence in the last decade. The causes of this metabolic disease include dysfunction and/or insufficient number of β cells. Existing diabetes mellitus treatments do not reverse or control the disease. Therefore, β-cell mass restoration might be a promising treatment. Severa

16. Induction and Morpho-Ultrastructural Analysis of Organogenic Calli of a Wild Passionfruit
This work studied a new protocol for organogenic calli induction and characterization of the morphology and ultrastructure of callogenesis in leaf explants of Passiflora gibertii N. E. Brown, a native passion fruit species from Brazil. Calli induction was performed in different growth conditions (light and dark), different MS medium salt concentrations (MS a

17. Progress in micropropagation of Passifloraspp. to produce medicinal plants: a mini-review
Micropropagation of Passiflora species and its hybrids may play an important role in the production of healthy and disease-free plants which can be a source of medicinal herbal products, nutritional fruits and ornamental flowers. The rapid multiplication of elite plants to obtain pharmacognostic material, containing valuable flavonoid C-glycosides, is possib

18. Organogenesis from in vitro-derived leaf and internode explants of Hoya wightii ssp. palniensis -a vulnerable species of Western Ghats
An efficient system was developed for indirect plant regeneration from in vitro-derived leaf and internode explants of Hoya wightii ssp. palniensis. Maximum percentage of the organogenic callus was obtained on MS medium supplemented with NAA (1.0 mg/l) and 2,4-D (2.0 mg/l). The best shoot bud induction was observed on MS medium with BA (1.0 mg/l) +IBA (0.5 m

19. Cultura de tecidos e transformação genética de espécies da família Poaceae / Tissue culture and genetic transformation of Poaceae family species
Brachiaria é um gênero de forrageiras da família Poaceae que apresenta plantas que se reproduzem por via sexual e assexualmente por apomixia,reprodução por sementes. A apomixia desperta interesse biológico e biotecnológico, pela perspectiva de levar esta característica de clonagem de plantas via sementes, a outras espécies. As cultivares plantadas d

20. Análise dos genes GHRH e GL12 em pacientes com deficiência de hormônio do crescimento congênita / GHRH and GLI2 genes analysis in patients with congenital growth hormone deficiency
Introduction: Alterations in genes related to GH secretion and pituitary organogenesis have been identified in patients with congenital GH deficiency (GHD). However, in only few cases of GHD the etiology has been established. GH-releasing hormone (GHRH) is an obvious candidate to explain isolated GH deficiency (IGHD). Previous reports in the literature did n

21. Efficient Regeneration of Eucalyptus urophylla x Eucalyptus grandis from Stem Segment
The aim of the present study was to establish an efficient regeneration system for the hybrid E. urophylla x E. grandis by means of organogenesis. Stem segments from seedlings were used as explants and cultured in a modified Murashige and Skoog medium (MS), supplemented with 13.2 µM N-phenyl-N'-[6-(2-chlorobenzothiazol)-yl] urea (PBU) and 0.285 µM indole-3

22. Otimização do crescimento e desenvolvimento de teca (Tectona grandis Linn f.) in vitro / Optimization of teak (Tectona grandis Linn f.) growth and development in vitro
O crescente aumento no uso da micropropagação de teca como forma de produção de clones com qualidades genotípicas e fenotípicas selecionadas a partir de árvores de elite, determinou a importância desse método, pois origina plantações com maior qualidade e uniformidade, agregando maior valor ao preço da madeira no mercado. O uso de sementes para a
