## factor,

in arithmetic, any number that divides a given number evenly, i.e., without any remainder. The factors of 12 are 1, 2, 3, 4, 6, and 12. Similarly in algebra, any one of the algebraic expressions multiplied by another to form a product is a factor of that product, e.g., a+b and ab are factors of a2b 2, since (a+b)(ab)=a2b2. In general, if r is a rootroot,
in mathematics, number or quantity r for which an equation f(r)=0 holds true, where f is some function. If f is a polynomial, r is called a root of f; for example, r=3 and r
of a polynomialpolynomial,
mathematical expression which is a finite sum, each term being a constant times a product of one or more variables raised to powers. With only one variable the general form of a polynomial is a0xn+a1x
equation f(x)=0, then (xr) is a factor of the polynomial f(x).

To clarify the effects of sanguiin H-6 on osteoclast formation, BMMs were cultured with indicated concentrations of sanguiin H-6 in the presence of M-CSF and RANKL for 72 h.
El M-CSF induce la proliferacion de los precursores tempranos de los osteoclastos, su diferenciacion y fusion a osteoclastos maduros e incrementa su supervivencia.
By culturing these cells with RANKL and M-CSF, we were also able to show that their potential to form osteoclasts (Figure 8B-C) and resorb bone (Figure 8D) was not affected by in vivo Pb exposure.
Mouse primary BMMs were obtained from the tibiae and femora of 7 week old ddY male mice and were cultured for 3 days in [alpha]-MEM containing 10% FBS and recombinant human M-CSF (1000 U/ml) in 100 mm tissue culture dishes.
Although much is known about the regulation of RANKL, OPG, RANK, and M-CSF expression by hormones and cytokines, it is not known which molecules regulate the expression of these cytokines during physiological remodeling.
