Comparative hemostatic parameters in BALB/c, C57BL/6 and C3H/He mice.
This study describes micro-methods to determine biological parameters in plasma of three strains of mice. Platelet count was significantly different among strains. C57BL/6 mice showed the highest values (988 x 10(3)/microL) and BALB/c the lowest (782 x 10(3)/microL). Fibrinogen levels were 2.55 (C57BL/6), 2.37 (BALB/c) and 2.28 g/L (C3H/He). Some inter-strain differences were observed in factor XIII (94, 118 and 114%) and plasminogen levels (142, 80 and 135%) in C57BL/6, BALB/c and C3H/He, respectively. Additionally, we observed individual mice factor XIII and plasminogen levels between 80 to 200% and 65 to 180%, respectively, in relation to pooled human plasma; and between 70 to 185% and 70 to 155%, respectively, against pooled mice plasma. To our knowledge, this is first report in the literature in diverse mice strains regarding hemostasis, mainly on factor XIII, plasminogen levels, and a very simple test that allows measurement of endogenous fibrinolytic activity present in the plasma. The different results are discussed in relationship with existing literature regarding if the animals in some studies were maintained under strict pathogen-free conditions, the collection of blood was from the heart or eye and if the analysis method was tested by counting manually or automatically. This work could contribute useful knowledge to the field of investigations regarding hemostatic disorders using mouse models, especially for laboratories that are not well equipped.
