Estradiol induces new dendritic spines and synapses on hippocampal CA1 pyramidal cells. Estradiol treatment resulted in a 46% increase in NMDA receptor binding. Estradiol treatment increases NMDA receptor binding in parallel with dendritic spine and synapse density. Estradiol treatment results in increased sensitivity of CA1 pyramidal cells to NMDA receptor-mediated synaptic input and that this increase is well correlated with the estradiol-induced increase in dendritic spine density in the apical dendritic tree of these cells. [1] 17 beta-estradiol is found to reduce Ba2+ entry reversibly via Ca2+ channels in acutely dissociated and cultured neostriatal neurons. 17 alpha-Estradiol also reduces Ba2+ currents but is significantly less effective than 17 beta-estradiol in rat neostriatal neurons. [2] 17 beta-estradiol exerts a dose-dependent inhibition of IL-1-, TNF-, and IL-1 and TNF-induced production of bioassayable IL-6. Estradiol inhibits both TNF-induced IL-6 production and osteoclast development in primary bone cell cultures derived from neonatal murine calvaria. [3] |

| In vivo | Estradiol mediates fluctuation in hippocampal synapse density during the estrous cycle in the adult rat. [4] Estradiol alone can reverse the ovariectomy-induced decrease in spine density. Estradiol combined with Progesterone initially increases spine density for a period of 2 to 6 hours but then results in a much sharper decrease than is observed following estradiol alone. [5] |

Bio Calculators
Molarity Calculator
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Dilution Calculator
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
