Beskrivelse: Stem cell factor (SCF) is an early-acting cytokine that plays a pivotal role in the regulation of embryonic and adult hematopoiesis. SCF promotes cell survival, proliferation, differentiation, adhesion, and functional activation of cells at multiple levels of the hematopoietic hierarchy. Together with other cytokines such as thrombopoietin and Flt3/Flk-2 Ligand, SCF is commonly used to promote expansion of primitive hematopoietic stem cells and multi-potent progenitor cells in culture (Martin <i>et al.</i>; Kent <i>et al.</i>). In synergy with various growth factors, including IL-2, IL-3, IL-6, IL-7, G-CSF, and erythropoietin, SCF increases proliferation and differentiation of myeloid and erythroid progenitor cells and a subset of lymphoid progenitor cells (Broudy). SCF is also a primary growth and activation factor for mast cells and eosinophils. SCF exists in two biologically active splice forms: a soluble and a transmembrane isoform. Upon binding to its receptor (c-Kit tyrosine kinase receptor; CD117), it activates PI3K, JAK/STAT, and MAPK pathways. SCF and signaling from c-Kit have also been reported to play an important role in pigmentation, fertility, vasculogenesis, motility of the gut via c-Kit positive interstitial cells of Cajal, and in the migration of neuronal stem and progenitor cells to sites of injury in the brain.

Beskrivelse: The exercise oscilloscope is placed at the Helmholtz coils so that its main axis coincides with the axis of the coils. A sawtooth-shaped voltage is applied to the deflection plates of the oscilloscope so that a smooth horizontal line appears on the screen. Let direct current pass through the coils at a preset anode voltage and adjust the intensity of the current so that the line is focused at one point. The specific charge e/m of the electron can be calculated from the measured values ​​of the anode voltage and the current through the coil.

Beskrivelse: Apparatus for detecting that the pressure at the bottom of a container does not depend on its design, but only on the liquid level. For quantitative determination of the hydrostatic pressure and examination of the linear relationship between pressure and liquid level. The liquid pressure at the bottom of the various vessels deforms a highly elastic rubber membrane whose movement is transmitted to a centimeter-graded needle. The deviation can be compensated with weights. The mass and distance of the weight from the pivot point make it possible to quantitatively determine the pressure change. A second pointer can be mounted vertically to visualize fluid level.

Produsent: EDUCATIONSCIENCE COLLECTION P

Beskrivelse: This vehicle coming straight from the year 2099 is running on clean hydrogen fuel using a next generation reversible Polymer Electrolyte Membrane (PEM) fuel cell. Its new design offers a futuristic feel for what transportation could look like in the next decades. Watch as oxygen and hydrogen gases are formed in two transparent containers in the back of the vehicle. The kit's fuel cell unit combines water electrolysis and fuel cell functions into one device. The car steers independently of the user once it hits a barrier, and cool blue LED lights flash from inside the cockpit.
