Introduction Based on previous researches, dental pulp stem cells (DPSCs) are easily accessible with limited morbidity after collection. Their embryonic origin, from neural crests, explains their multipotency. DPSCs are primarily derived from the pulp tissues of the teeth.Objective: This study was undertaken to isolate, culture, and characterize two different third molar and first premolar hum...

to evaluate the effects of planting date and plant density on morphological characteristics, including essential oil content of ajowan (trachyspermum ammi) a study was conducted during the years 2003 and 2004 at the experimental farm, faculty of agriculture, ferdowsi university of mashhad. treatments were laid out in a factorial form based on a complete randomized block design of three replicat...

Neural stem cells (NSCs) as a heterogeneous multipotent and self- renewal population are found in different areas in the developing mammalian nervous system, as well as the sub-ventricular zone (SVZ) and the hippocampus of the adult brain. NSCs can give rise to neurons, astrocytes and oligodendrocytes. The aim of this study was to differentiate neural stem cells into noradrenergic–like cells in...

objective(s): granulocyte-colony stimulating factor (g-csf) is used in clinical practice for the treatment of neutropenia and to stimulate generation of hematopoietic stem cells in bone marrow donors. in the present study, the ability of g-csf in mobilizing exogenous bone marrow stem cells (bmscs) from peripheral blood into the brain was tested. we for the first time injected a small amount of ...

to investigate effect of calcium and growth medium on lilium (asiatic hybrid lilium bulbs “tresor” cultivar) and nutrients uptake, a factorial experiment based on completely randomized design was conducted by three levels of calcium in nutrient solution (2, 4 and 6 mm*) and five growth media (100% perlite, 70% perlite + 30% cocopeat, 50% perlite + 50% cocopeat, 30% perlite + 70% cocopeat, 100% ...

one of the most important operations in managed gardens is pruned grapes. for evaluate the effect of pruning short, medium, heavy on yield and yield components of taif grapes, before and after the cold winter, in the years 2012 to 2013, a factorial experiment in a crbd design with five replicates were performed on two factors. the first factor was the number of buds per stem and included the th...

in order to investigate the effect of pruning and potassium nutrition on pumpkin grain yield and quality, a factorial experiment based on complete block design with four replications was carried out in nooshar village of ardabil province, ardabil, iran, in 2007. experimental factors include potassium nutrition in three level (0, 75 and 150 kg/ha from potassium sulfate) and stem pruning (without...

this experiment was conducted to investigate the genetic diversity, relationship between morphological, agronomic and qualitative traits and to identify components of forage yield using some multivariate statistical methods in local sainfoin populations. the experiment was conducted as randomized complete block design with four replications in isfahan university of technology research farm. res...
