Table 1.

Fenestration pattern in different species Brief overview of fenestrae characteristics of different species. Notice the large variations in diameter and number of fenestrae between the different species. The reported data from this table were obtained by at random measurements along the sinusoids. "n.d." = no data available. Data are expressed as mean ± S.D. In case of baboon, human and rainbow trout the data correspond with the minimum and maximum diameter or number of fenestrae measured.

Species (ref.)	Diameter (nm)	Number of fenestrae / μm2
Rat [25]	98.0 ± 13.0	20.0 ± 6.3
Mouse [26]	99.0 ± 18.0	14.0 ± 5.0
Rabbit [27]	59.4 ± 4.8	17.3 ± 3.8
Chicken [23]	89.6 ± 17.8	2.9 ± 0.3
Baboon [20]	92 – 116	1.4 – 1.9
Human [28]	50 – 300	15 – 25
Rainbow trout [21]	75 – 120	n.d.
Sheep [29]	60.0 ± 1.9	n.d.
Goat [30]	n.d.	n.d.
Cat [31]	n.d.	n.d.
