HUVEC migrate towards C.M. of U-87 MG cells (red bar) at a significantly increased rate ( p = 1.6×10 −13 ) compared with that of Clone #1 (black bar). <t>DMEM</t> containing 10% <t>FBS</t> served as positive control; DMEM served as negative control. C. HUVEC’s ability to form capillary-like tube structures on Matrigel® is significantly higher ( p = 0.001) in the presence of C.M. of U-87 MG cells (red bar) compared with that in the presence of C.M. of Clone #1 cells (black bar).

    Fusion potential of cultured myoblasts in different media. After passage 3, cells cultured in 2 different media were seeded in duplicate into 96-well plates, and when 80% confluence was obtained, the culture medium was switched to fusion medium [Dulbecco’s modified Eagle’s medium (DMEM), 2% fetal bovine serum <t>(FBS),</t> 25 μ mol/l insulin] and changed every 3 days. After 11 days, cells were fixed and stained with Wright’s eosin methylene blue solution. The number of nuclei in the 6 largest myotubes was counted in each well. Additionally, cells cultured in DFEFH medium were subjected to higher passages and their fusogenic potential was assessed in a similar manner.

    Effect of trypsin on NLP formation. NLP were prepared by adding 1 mM of CaCl 2 , Na 2 CO 3 , and NaH 2 PO 4 to DMEM containing the indicated amounts of serum, in the presence or absence of 0.5% trypsin, followed by incubation at 37°C for 1 day (A–D) or 3 days (E–H). Trypsin was shown not only to release the inhibition caused by FBS or HS, but also to produce a dose-dependent increase in the amount of precipitation that increased with the serum dosage. (I) Trypsin treatment on NLP as demonstrated by SDS-PAGE. NLP formed as in Fig. 9 from 3 mM each of the 3 precipitating reagents as well as 1% FBS in DMEM, either in the absence (lane 1) or presence (lane 2) of 0.5% trypsin. After overnight incubation of the 1 ml incubation mixture at 37°C, 100 µl was removed, pelleted by centrifugation, and washed twice in DMEM, and resuspended in 16 µl of 50 mM EDTA in double-distilled water for SDS-PAGE. Lane 3 contains 5 µg of trypsin, as control, which shows as a 25 kDa band. Note a prominent 72 kDa band and two fainter 54 kDa and 30 kDa bands associated with FBS NLP (lane 1), all of which disappears with trypsin treatment (lane 2).

    Effect of serum, temperature, and EDTA on NLP formation. NLP were prepared from 3 mM of CaCl 2 , Na 2 CO 3 , and NaH 2 PO 4 in DMEM containing different amounts of FBS or HS, as indicated, followed by incubation at 37°C for 1 day (A and B), 1 week (E and F), or 4°C for 2 weeks (C and D). Note that FBS had a stronger, dose-dependent inhibitory effect on NLP formation in all 3 situations when compared with HS. Inhibition could be seen for 2 weeks at 4°C, but at 37°C, it was overcome after 1 week, and this release of inhibition was more evident with HS. (G ) NLP were prepared exactly as in Fig. 1B , by adding solutions of 0.25 M CaCl 2 , Na 2 CO 3 , and NaH 2 PO 4 (pH 7.4) to DMEM to the indicated concentrations in the presence of 10 mM EDTA, followed by incubation for 1 day. Addition of EDTA into the precipitation mix decreased the amount of NLP, except for well 6, containing 10 mM of precipitating reagents, indicating that excess EDTA is needed for the inhibition to work.

    Protein profiles of NLP and NB as determined by their passage through serum-free or serum-containing medium. (A) Protein profile of HS NB maintained in DMEM containing 5% HS (lane 1) followed by transfer to serum-free DMEM and incubation for 1 day (lane 2), 4 days (lane 3), and 6 days (lane 4), after which proteins were analyzed by SDS-PAGE. A gradual disappearance of proteins bands is seen with increased incubation time in serum-free medium. (B) Protein profile of NB strain DSM 5821 after 1 day in DMEM containing 2% FBS (lane 1), followed by transfer to serum-free DMEM for 1 day (lane 2), 4 days (lane 3), and 6 days (lane 4), again showing a gradual disappearance of bands. (C) Protein profiles of NB obtained from 10% HS as in Fig. 3 (lane 1) and HS NLP formed as in Fig. 3 except that 5% HS was present in the precipitating mixture (lane 2). HS NLP were then transferred to DMEM containing 5% HS and incubated for the following periods of time: 1 hr (lane 3), 1 day (lane 4), 4 days (lane 5), 10 days (lane 6), and 14 days (lane 7). A gradual increase of bands of low molecular weight could be seen along with a fading of the high molecular weight bands, especially the 70–72 kDa band. (D) Protein profiles of NB strain DSM 5820 maintained in 10% γ-irradiated FBS (lane 1) and FBS NLP obtained as in Fig. 3 , except that 5% FBS was added to the precipitating mixture (lane 2). FBS NLP were inoculated into DMEM containing 5% FBS and incubated for the following periods of time: 2 hr (lane 3), 1 day (lane 4), 4 days (lane 5), 10 days (lane 6), and 14 days (lane 7). By day 14, the protein profile of these FBS NLP, with an increase in the number of bands and a loss of the 70–72 kDa band, closely resembled that of DSM 5820 (lane 1).

After incubating for 1 month at 37°C, NB were detected by visual inspection and A 650 (insets). For FBS, the amount of NB was maximal at 0.3%, decreasing thereafter with higher FBS concentrations, while for HS, NB were only visually noticeable at HS concentrations exceeding 3%.

NLP were prepared by successively adding solutions of 0.25 M CaCl 2 , Na 2 CO 3 , and NaH 2 PO 4 (pH 7.4) into DMEM as indicated and incubated at 37°C overnight, which resulted in dose-dependent formation of NLP (top row). The same experiment was repeated in the presence of 1% FBS, which showed inhibition of NLP formation (bottom row). This serum inhibition was overcome by increased concentrations of precipitating reagents, at 3 mM and above.

( B ) HT1080 cells were pretreated with Catalyser-21 TM for 24 h and then inoculated at 1 × 10 5 cells/well of the Matrigel chamber. The chambers were incubated at 37°C for 12 h, after which the cells that had invaded the lower collagen surface were fixed and stained with Diff-Quick (Sysmex, IL, USA). The invading cells were counted in three random fields under a light microscope. Differences were analyzed by Student’s t test (values are the mean ± SD; n = 3) and the asterisk represents a significant difference compared with the control (* p

The culture medium was replaced by fresh serum-free MEM containing Catalyser-21 TM and the cells were incubated for another 24 h. Total RNA was purified from Catalyser-21 TM -treated and untreated HT1080 cells and used for RT-PCR templates. Amplified products were resolved by agarose gel electrophoresis and analyzed as described in the legend of Fig. 3. Lane a, DNA fragments amplified from total RNA of untreated HT1080 cells.

    In vitro lactic acidosis affects IFN-α production by pDCs. pDCs purified from buffy coats of HD were cultured in RPMI 1640 medium supplemented with 10% FBS and IL-3 plus lactic acid (10 mM; 15 mM; 20 mM) ( n = 7; ( A )) or hydrochloric acid (pH = 7.4; 7.0; 6.5; 6.0; 5.5) ( n = 7; ( B )) for 24 h. pDCs were stimulated with R848 for 2 h. Intracellular IFN-α was analyzed by flow cytometry. Aligned dot plot graphs show the percentages of IFN-α + pDCs evaluated on BDCA-2 + /CD123 + cells. Bars represent the mean of biological replicates. The statistical significance was calculated by two-sample paired sign test. * p

    Frequency of interferon alpha (IFN-α) and CXCL10-producing plasmacytoid dendritic cells (pDCs) in chemo-naïve MM patients and HD. Representative dot plots of R848-stimulated IFN-α + and CXCL10 + pDC subsets obtained from HD and MM patients are shown ( A ). PBMCs were isolated from peripheral blood of HD ( n = 25) and MM patients ( n = 29). Total PBMCs were cultured in RPMI 1640 medium supplemented with 10% FBS and IL-3 and stimulated with R848 or IMQ for 2 h ( B , D ) and 6 h ( C , E ), and with CpG-ODN 2216 for 6 h ( B – E ). IFN-α ( B , D ) and CXCL10 ( C , E ) were analyzed by intracellular flow cytometry staining. Scatter dot plot graphs illustrate the percentages of positive pDCs evaluated on BDCA-2 + /CD123 + cells. Subgroup analysis of the MM cohort illustrating the frequency of IFN-α + and CXCL10 + pDCs in M1a-c categories ( D , E ). Median and IQR are shown in ( B , C ). Mean and SD are shown in ( D , E ).

    Fusion potential of cultured myoblasts in different media. After passage 3, cells cultured in 2 different media were seeded in duplicate into 96-well plates, and when 80% confluence was obtained, the culture medium was switched to fusion medium [Dulbecco’s modified Eagle’s medium (DMEM), 2% fetal bovine serum (FBS), 25 μ mol/l insulin] and changed every 3 days. After 11 days, cells were fixed and stained with Wright’s eosin methylene blue solution. The number of nuclei in the 6 largest myotubes was counted in each well. Additionally, cells cultured in DFEFH medium were subjected to higher passages and their fusogenic potential was assessed in a similar manner.
