Overview page represent trading in all U.S. Indexes: Index quotes may be real-time or delayed as per exchange requirements refer to time stamps for information on any delays.

International stock quotes are delayed as per exchange requirements. stock quotes reflect trades reported through Nasdaq only comprehensive quotes and volume reflect trading in all markets and are delayed at least 15 minutes. Dividend Yield A company's dividend expressed as a percentage of its current stock price. Restricted stock typically is that issued to company insiders with limits on when it may be traded. To calculate, start with total shares outstanding and subtract the number of restricted shares.

Public Float The number of shares in the hands of public investors and available to trade. Shares Outstanding Number of shares that are currently held by investors, including restricted shares owned by the company's officers and insiders as well as those held by the public. For companies with multiple common share classes, market capitalization includes both classes. Market Cap is calculated by multiplying the number of shares outstanding by the stock's price. Market Capitalization Reflects the total market value of a company. Earnings Per Share (TTM) A company's net income for the trailing twelve month period expressed as a dollar amount per fully diluted shares outstanding. Till at the University of Toronto in the 1960s.P/E Ratio (TTM) The Price to Earnings (P/E) ratio, a key valuation measure, is calculated by dividing the stock's most recent closing price by the sum of the diluted earnings per share from continuing operations for the trailing 12 month period. Research into stem cells grew out of findings by Ernest A. Embryonic cell lines and autologous embryonic stem cells generated through somatic cell nuclear transfer or dedifferentiation have also been proposed as promising candidates for future therapies.

Stem cells can now be artificially grown and transformed (differentiated) into specialized cell types with characteristics consistent with cells of various tissues such as muscles or nerves. By definition, autologous cells are obtained from one's own body, just as one may bank his or her own blood for elective surgical procedures.Īdult stem cells are frequently used in various medical therapies (e.g., bone marrow transplantation). Of all stem cell types, autologous harvesting involves the least risk. Stem cells can also be taken from umbilical cord blood just after birth.

There are three known accessible sources of autologous adult stem cells in humans:īone marrow, adipose tissue, and blood. In a developing embryo, stem cells can differentiate into all the specialized cells-ectoderm, endoderm and mesoderm (see induced pluripotent stem cells)-but also maintain the normal turnover of regenerative organs, such as blood, skin, or intestinal tissues. In adult organisms, stem cells and progenitor cells act as a repair system for the body, replenishing adult tissues. In mammals, there are two broad types of stem cells: embryonic stem cells, which are isolated from the inner cell mass of blastocysts, and adult stem cells, which are found in various tissues. Stem cells are cells that can differentiate into other types of cells, and can also divide in self-renewal to produce more of the same type of stem cells.
