Calcium Supplementation

Calcium supplementation is the use of calcium-containing products to increase calcium intake when dietary sources do not meet physiological needs, making it relevant to bone biology and mineral homeostasis. After ingestion, calcium is absorbed primarily in the intestine, where vitamin D promotes transport into the bloodstream; parathyroid hormone helps regulate circulating calcium by coordinating intestinal absorption, renal conservation, and release from bone. Calcium ions support hydroxyapatite formation in the skeleton and also participate in muscle contraction, neurotransmitter release, and cell signaling. In biology research and clinical studies, supplementation helps investigate bone development, deficiency, mineral metabolism, and strategies for maintaining skeletal health.

We present a method to isolate rapid (microsecond) calcium events from slower fluxes in living cells using laser scanning confocal microscopy. The method measures fluorescence intensity fluctuations of calcium indicators by recording line scans of several hundred pixels in a cell. Histogram analysis allows us to isolate the time scales of different calcium fluxes.

Calcium Imaging in Neurons

Calcium ions play an integral role in neuron function: They act as intracellular signals that can elicit responses such as altered gene expression and neurotransmitter release from synaptic vesicles. Within the cell, calcium concentration is highly dynamic due to the presence of pumps that selectively transport these ions in response to a variety of signals. Calcium imaging takes advantage of intracellular calcium flux to directly visualize calcium signaling in living neurons.This video begins...
