Pages H1771-H1777: Ng CP and Swartz MA. "Fibroblast alignment under interstitial fluid flow using a novel 3-D tissue culture model" An incorrect value for viscosity was used, and thus the values for Darcy permeabilities (K') and shear stresses were incorrectly listed in the paper. Corrections are the following:
Page H1772: The sentence in the right column, paragraph 2, line 3 should read as "The flow was delivered at 12 µl/min..."
Page H1773: The sentence in the left column, paragraph 2, line 7 should read as "...µ is the viscosity of the perfusing fluid [equals 0.75 cp as determined using an Ubbelodhe viscometer (Cannon Instrument; College Station, PA)]"; line 17 should read as "...because the PE has a value of K' that was two orders magnitude greater than that of the gel (107 vs. 109 cm2, respectively)." The sentence in the right column, paragraph 3, line 16 should read as "The estimated shear stress (30) on the cells in the collagen matrix varied from 0.4 to 0.1 dyn/cm2 (at ri to ro, respectively)."
Page H1774: The sentence in the left column, paragraph 1, line 6 should read as "This flow rate yielded a range of shear stresses on the surface of 3.7-1.0 x 104 dyn/cm2 from ri to ro." The sentence in the right column, line 11 should read as "However, K' eventually decreased before it leveled off at a steady value of
1.6 x 1010 cm2 by day 5. On the other hand, the K' for the acellular gel under interstitial flow initially increased and leveled off at
2.7 x 109 cm2."
Page H1775: The scale of the y-axis in Fig. 5 should be 0 to 4 x 109 cm2.
Page H1776: The sentence in the left column, paragraph 2, line 19 should read as "Moreover, the measurements of K' were consistently found in the narrow range of 0.163.0 x 109 cm2, suggesting that... ." The sentence in the left column, paragraph 3, line 3 should read as "... are generally estimated to be in the range of 1011 to 1015 cm2 (15), with mouse tail skin recently estimated at 1011 cm2 (27)."
